An earthquake and microtremor isolation floor system has been developed
for high-tech facilities such as computer rooms, VLSI factories and those
manufacturing laser-technology-applied products. The system consists of
three-dimensional isolators, air dampers, viscous dampers and leveling
controllers which automatically maintain the level of the floor. The
three-dimensional isolator, made of compound construction of an air spring
and a laminated rubber bearing, absorbs vertical vibration with the air
spring and horizontal vibration primarily with the laminated rubber
bearing. To examine the effectiveness of the system, seismic-shaking tests
and microtremulous tests on the floor model weighing 20 tons were
conducted. The results are satisfactory and effective isolation of both
earthquake and microtremor is confirmed. Furthermore, it is observed that
numerical predictions are in good agreement with experimental results.

Forced vibration field tests and finite element studies have been
conducted on Morrow Point (arch) Dam in order to investigate dynamic
dam-water interaction and water compressibility. Design of the data
acquisition system incorporates several special features to retrieve both
amplitude and phase of the response in a low signal to noise environment.
These features contributed to the success of the experimental program

which, for the first time, produced field evidence of water
compressibility; this effect seems to play a significant role only in the
symmetric response of Morrow Point Dam in the frequency range examined. In
the accompanying analysis, frequency response curves for measured
accelerations and water pressures as well as their resonating shapes are
compared to predictions from the current state-of-the-art finite element
model for which water compressibility is both included and neglected.

The purpose of this work was to determine the structural properties
(stiffness and damping) of low aspect ratio shear wall structures that can
be used in lumped mass models to predict their dynamic response.
Instrumentation was used to separate the deformation of the structures into
components caused by shear and components caused by bending so that
individual components of stiffness can be examined. Results from these
experiments showed that the current industry standard of using a stiffness
based on an uncracked cross-section, strength-of-materials analysis,
neglecting the reinforcement, and including shear deformation is
appropriate prior to cracking. After cracking, the stiffness was shown to
be a function of load level, past load history, and the amount of
reinforcement. 96 refs., 53 figs., 12 tabs. (ERA citation 14:020064)

This paper presents selected elements of a laboratory prototype of a new
in situ geotechnical testing system. The testing system, currently under
construction, is intended to provide improved measures of the in situ
nonlinear shear stress-strain characteristics of the upper layers of a soil
deposit. Such information is needed for earthquake site response analysis
procedures used to predict the behavior of sites during earthquakes. Such
procedures are commonly used at the advanced stages of the earthquake
resistant design of critical soil-structure-equipment systems (offshore
structures, hospitals, dams, etc.) The elements of the testing system
described in this paper are elements intended to help preserve in situ
conditions. 5 refs., 3 figs. (ERA citation 14:018463)

The scope of this study is to perform for the Savannah River site the
same kind of calculation as performed for the Nuclear Regulatory Commission
(NRC), using the same methods and data, as those used for all the active
Nuclear Power Plant (NPP) sites located east of the Rocky Mountains. The
study was specifically designed to provide a set of tools with which the
hazard at all the plant sites in the Eastern United States (EUS) could be
estimated. However it must be noted that the very specific characteristics
of each plant site 'are only accounted for in a generic fashion. For
example, the local site corrections used eight different site categories
rather than any site specific factors. In addition, the models of
rp
11@

seismicity developed did not concentrate on any specific site locations,
but were provided for the entire EUS. Similarly, the ground motion models
used in the analysis did not concentrate on small regions, rather, they
were separated in four different groups of models applicable to the four
areas in the EUS, namely the Northeast, the Southeast, North central, and
South central EUS. The results provided by the NRC/LLNL methods with the
present data banks are accurate enough that they can be used in screening
techniques and for preliminary types of analyses. If a detailed site
specific analysis were deemed necessary at a site, a careful revisiting and
possibly updating of each of the links in the chain of analyses leading to
the final data base would be appropriate. 2 refs., 105 figs., 1 tab. (ERA

took place as a result of the Whittier Narrows earthquake and determine
ignition rates as a function of Modified Mercalli Intensity. Using this
information and a complex fire modeling algorithm, the potential for
conflagration can be developed. The objectives of the study were to: (1)
count the number of ignitions; (2) describe them as to intensity region and
location about the epicenter; and (3) identify the sources of the
ignitions, such as electrical, gas, or flammable liquid spills.

A computer program, TARA-3, developed for conducting nonlinear hysteretic
dynamic response analysis is presented. The program can operate in either a
total or effective stress mode. It may be used to analyze the seismic
response of earth structures and soil-structures interaction systems such
as nuclear containment structures. Validation studies of TARA-3 using data
from seismic tests on centrifuged models are described. These studies
confirm the capability of TARA-3 to predict accelerations, porewater
pressures, and displacements in complex soil-structures systems during
seismic loading with acceptable accuracy and reliability for engineering
design. Keywords: Earth quake engineering; Nonlinear dynamic analysis;

As part of an ongoing program, Lawrence Livermore National Laboratory
(LLNL) is directing the Natural Phenomena Hazards Modeling Project (NPHMP)
on behalf of the Department of Energy (DOE). A major part of this effort is
the development of probabilistic definitions of natural phenomena hazards;
seismic, wind, and flood. In this report the first phase of the evaluation
of flood hazards at DOE sites is described. Unlike seismic and wind events,
floods may not present a significant threat to the operations of all DOE
sites. For example, at some sites physical circumstances may exist that
effectively preclude the occurrence of flooding. As a result, consideration
of flood hazards may not be required as part of the site design basis. In
this case it is not necessary to perform a detailed flood hazard study at
all DOE sites, such as those conducted for other natural phenomena hazards,
seismic and wind. The scope of the preliminary flood hazard analysis is

restricted to evaluating the flood hazards that may exist in proximity to a
site. The analysis does involve an assessment of the potential encroachment
of flooding on-site at individual facility locations. However, the
preliminary flood hazard assessment does not consider localized flooding at
a site due to precipitation (i.e., local run-off, storm sewer capacity,
roof drainage). These issues are reserved for consideration by the DOE site
manager. 11 refs., 84 figs., 61 tabs. (ERA citation 13:051370)

U.S. Naval shipyards where submarines are dry-docked are located in
regions of the United States where significant earthquakes are known to
occur. The graving dry-docks at these shipyards are currently designed to
withstand earthquake accelerations up to 0.26 g1s. This thesis develops a
nonlinear material model for wood drydock block caps which more closely
represents its actual behavior than linear elastic material models used
previously. Using this non-linear model, it is determined that submarine
drydock blocking systems would fail at even lower earthquake accelerations
than that predicted by linear material models. This confirms that submarine
drydock blocking systems would fail at accelerations which are
significantly lower than the Navy's 0.2 g survival requirement. New
blocking materials are then analyzed using non-linear models developed in
this thesis in order to determine their potential for increasing system
survivability. The materials analyzed are natural rubber and dynamic
isolators. It is determined that when these materials are incorporated in
the blocking systems, significant increases in survivability occur;
however, all the systems still fall well below the required 0.2 g level.
This thesis makes it clear that the current submarine drydock blocking
systems provide inadequate protection of the submarines from accelerations
caused by highly probable earthquakes, but the use of new blocking
materials can reduce the risk of blocking failure. (KT/AW)

Institute of Technology. The test results, which revealed significant
soil-structure interaction, were predicted reasonably well by finite
element models of both bridge-soil systems. Further research would be
helpful to: (1) complete the understanding of the behavior of monolithic
abutments during lateral seismic loading; and (2) translate the results
into a design guide suitable for direct use by the bridge engineer.

For seismic design of structures, earthquake input is usually defined in
terms of pseudo acceleration response spectra. However, recent research has
identified the need of defining the design input in terms of the relative
velocity and relative acceleration response spectra as well. Furthermore,
for the equivalent linear analysis of hystertically behaving structures,
one also needs to define the response spectra of a massless oscillator.
Based on the analysis of available earthquake records, the study defines
the above mentioned response spectra as the seismic design input for
(10)

various site conditions. The available earthquake records are classified
into five groups according to their site stiffness and epicentral distance
as the grouping parameters. The motion parameters of average frequency and
significant duration are obtained for each group and their effect on the
response spectra is studied. Correlation analyses between various ground
motion characteristics such as peak displacement, velocity, acceleration
and root mean square acceleration are also carried out for each group. It
is shown that the relative spectra can be reliably estimated from the
pseudo spectra. The site dependent design spectra are defined for a wide
range of oscillator periods and damping ratios.

Attention is focused on a wall model recently proposed by Japanese
researchers. The model, based on a macroscopic approach, idealizes the
generic wall member as three vertical line elements with infinitely rigid
beams at the top and bottom floor levels. The two outside elements are
truss elements to represent the axial stiffness of the boundary columns;
the central element is a one-component model constituted by horizontal,
vertical and rotational springs to represent, respectively, the shear
stiffness of the wall, the vertical axial stiffness and the flexural
stiffness of the central panel. Modifications of the wall model are
developed in the studies reported. The main modification is aimed at
improving the simulation of the hysteretic behavior of the axial elements
adopted by the Japanese. These axial elements are replaced by new elements
which simulate more closely the hysteretic behavior of a reinforced
concrete (R C) column member under axial load reversals. In order to check
the effectiveness and reliability of the modified wall model, a numerical
investigation is carried out by calibrating the results against measured
behavior of a series of R C structural walls that have been tested at the
University of California at Berkeley. The modified wall model proves to be
effective and suitable for incorporation in a practical nonlinear analysis
of R C multistory structural systems.

Despite it's extensive use, low tensile strength has been recognized as
one of the major drawbacks of concrete. Although one has learned to avoid
exposing concrete structures to adverse static tensile loads, these
structures cannot be shielded from short duration dynamic tensile loads.
Such loads originate from sources such as impact from missiles and
projectiles, wind gusts, earthquakes and machine vibrations. In addition,
modern computer-aided analysis and use of concrete for special structures
such as reactor containment vessels, missile storage silos and fall-out
0)

shelters, has led to a growing interest in the cracking behavior of
concrete. Experimental results indicate that the fracture strength and
cracking behavior of concrete are affected by the rate of loading. To
accurately predict the structural response under impact conditions, the
knowledge of behavior of concrete at high rates of loading is essential.
Using a two degree of freedom model guidelines were developed for designing
an impact test setup, thus enabling one to conduct impact tests free of
adverse inertial effects. Based on these guidelines, the author has
developed an instrumented modified Charpy impact testing system. This
experimental test setup was used to obtain basic information such as
load-deflection relationship, fracture toughness, crack velocity (measured
using 'Krak Gages'), and load-strain history during an impact fracture
event of plain concrete and SFRC.

A necessary design element for buildings and other structures subjected
to strong ground motions due to earthquakes is an estimate of the frequency
and intensity of earthquakes expected to occur in the region during the
economic life of the structure. It is also necessary to estimate the ground
motion response at a site, given that an earthquake of a certain size and a
certain distance away from the site occurs. Recognizing the random nature
of earthquake occurrences, and the limited understanding of the physical
processes leading to seismic loading at a site, analytical models have been
developed to predict the probability of exceeding a given level of ground
motion during a specified period. The report presents the results of
initial (Phase I) efforts to refine and improve state-of-the-art models for
predicting ground motion responses, and ultimately, to improve subsequent
seismic hazard estimates.

Two scale-model structures representing an idealized auxiliary building
were seismically tested. The scales (1/42, 1/14) were chosen so that both
structures were models of the prototype, and the 1/42-scale model was a

1/3-scale model of the 1/14-scale structure. Both models were constructed
out of microconcrete. The 1/42-scale used wire mesh to simulate
reinforcing, and the 1/14 scale used model deformed bars. The general
result verified previous test experience in the program: the frequency
response of these structures, when subjected to seismic design loads, will
be below that predicted from the structural analysis. The implication of
the result for equipment and piping is under investigation. The
recommendation of the program, based on testing thus far, is to verify the
conclusions on larger real concrete structures of a geometry that will be'
agreed upon by the technical review group for the program.

Studies are presented which indicate the feasibility of an in situ
testing procedure for determining in situ cyclic and dynamic soil
properties. The properties are to be described in the detail and with the
accuracy appropriate for later stages of the analysis and design of
important, earthquake-resistant, soil-structure-equipment systems. The
procedure is intended to allow more effective use of analysis procedures
used to predict system behavior during earthquakes. One study in which
tests were simulated analytically indicates theoretical feasibility. A
second study indicates operational and economic feasibility. Items were
identified which could create added uncertainty in inferring soil
properties, but the added uncertainty was judged to be only modest.

During earthquakes, ground movement can cause soils to lose strength or
stiffness resulting in structures settling and embankments sliding. A
phenomenon contributing to this loss in strength and subsequent failures is
called soil liquefaction. This title, however, does not refer to a single
well-defined event, but rather to a complex set of interrelated phenomena
which contribute to the occurrence of damage and and failures during an
earthquake. Numerous investigators have tried to model and predict the
potential and probability of liquefaction occurring in soils. Since the
early 1960's considerable attention has been given to the development of
laboratory testing procedures to provide improved methods of characterizing
the liquefaction properties of soils. Various test apparatus have been
designed or modified in an attempt to provide an accurate representation of
the stress state generated in-situ by earthquakes. To this end a number of
experimental devices including the cyclic triaxial, and cyclic simple shear
with repeatable representation of conditions in-situ during an actual
earthquake.

This citation summarizes a one-page announcement of technology available
for utilization. Ninety-seven percent of all security alarms triggered each
year in the country are false because of improperly designed sensor systems
and faulty sensor installations, according to security experts at the Naval
civil Engineering Laboratory (NCEL). Sensors are set off by
non-threatening, unintended disturbances. A motion sensor could be
triggered by a sudden gust of wind, or a vibration sensor could be
activated by a small earthquake or a passing vehicle. Most alarms detect
only the physical presence of intruders inside a building but fail to sound
warnings when intruders are still outside attempting to gain entry. NCEL is
developing data that will determine the capabilities of various sensors for
use in formulating building design guidance. The new test data could lead
to development of a new technology featuring more sophisticated early
warning sensors. The advancement could result in increased alarm
reliability (perhaps 50 percent in the far future compared to today's
meager 3 percent) and overall improved security. NCEL's investigation into
sensors and their sensitivities focuses on a unique structure constructed
of four different building materials (wood, brick, concrete block, and
concrete).

Physical model tests were performed on homogeneous cohesionless
embankments subjected to idealized ground motion. During the testing, the
response of model embankments to a sinusoidal input motion was monitored,
and acceleration and displacement data were collected. An analytical model,
based on Newmark's sliding block theory, was used to estimate the permanent
displacement of sliding blocks subjected to input dynamic motion.
Analytical results were compared with physical model test results to assess
the validity of the mathematical model. It was concluded that the
mathematical model did not accurately predict the deformation of
homogeneous cohesionless embankment models because of difficulty in
determining the effective shear strength of the material at low normal

stresses.

The primary Supernatant Treatment System (STS) confinement barriers have
sufficient reserve capacity, due to the inherent safety factors associated
with this type of construction, to survive extreme environmental loading
(e.g., design basis earthquake and tornado events) without structural
failure and leakage of high-level wastes into the environment. The primary
confinement barriers of highest reliability under earthquake and tornado
loading are the reinforced concrete vaults and chambers that enclose the
STS process vessels and piping. These buildings and tank vaults have been
designed to higher structural safety standards than required for life
safety by local building codes used in the design of industrial process
plants in New York state. The radiological shielding requirements generally
resulted in structural member sizes and wall thicknesses that were larger
and consequently stronger than found in conventional industrial plant
building design. The margin of safety against failure of the reinforced
concrete barriers is conservatively estimated at 2 to 4 times the design
basis earthquake. The least predictable element in the building barrier is
the PVC water stop between the STS building and the shield structure on
tank vault 8D-1. Tests and analysis indicate the water stop has an
estimated safety factor against rupture under earthquake of 3 or greater.
In terms of the internal piping and vessel systems that confine the raw
supernatant in its process flow path, the connecting piping between the
valve aisle, pipeway and shield structure appears to be the most vulnerable
under earthquake. The safety factor for the piping appears to be on the
order of 3. 26 refs. (ERA citation 12:036507)

A computer code (RASCAL) has been developed to provide realistic
predictions of ground motion parameters for applications to earthquake
engineering risk assessment. The code incorporates random vibration theory
(RVT) to calculate peak value of acceleration and velocity in addition to
response spectra for specified earthquake source and propagation path
parameters. To generate synthetic time histories, the code combines the
phase spectra from observed strong motion records to a theoretical Brune
modulus. The above techniques are also employed to produce an acceleration
time history whose response spectrum matches a specified target or design
response spectrum.

implementing to reduce their earthquake risk. Japan's historic seismic
activity is discussed as well as perception of earthquakes, prediction of
earthquakes, and the public education program. Attention is directed to the
regulations pertaining to disaster preparedness in Japan. Activities of the
government of Shizuoka Prefecture are discussed, in particular the role
this prefectural government plays in promoting earthquake hazard reduction
among industries by providing financial incentives, and both planning and
technical guidance. The organizational and engineering measures implemented
at the Shizuoka General Hospital are discussed. The hospital, in the Tokai
Region, was designed and built after the prediction of a major earthquake
in the region. Earthquake damage incurred by the petroleum industry and
measures taken by this industry to minimize damage in the future are
discussed. Products developed by private industry specifically for
earthquake hazard reduction are identified.

In the study a mathematical model is proposed to predict the nonlinear
in-plane behavior of clay brick masonry walls when subjected to dynamic
excitations. The study has two stages: the development of the form of the
mathematical model, and the establishment of the parameter functions
appearing in the model both using optimization and experimental data. The
experimental work was carried out using the shaking table of the Earthquake
Engineering Research Center, University of California, Berkeley. The
experiments involved in-plane horizontal earthquake excitations. The
intensity of excitation, starting with a small value, was increased
gradually through the beginning of cracking until damage is complete. Time
histories of accelerations and displacements relative to a fixed frame were
recorded at the upper and lower edges, and at the mid-length of the wall
specimen.

The behavior of reinforced concrete (R/C), Category I noncontainment
nuclear power plant structures subjected to seismic events of magnitude
greater than used in their original design has been investigated using two
sizes of scale models. Test results were analyzed to determine (1) maximum
input for the response to remain linear/elastic; (2) changes in stiffness,
damping, and modal frequency that are produced by seismic input greater
than that causing linear elastic response; (3) changes in floor response
spectra when the structure's response is nonlinear/inelastic; and (4) the
magnitude of the seismic event necessary to fail (excessively crack) these
structures. By constructing models of two sizes, it was possible to make
two independent predictions of prototype behavior and to compare the
results from the two models. 1 ref., 4 figs., 1 tab. (ERA citation

This* report presents a state-of-the-art model for inelastic response
analysis of braced steel structures. This model achieves realism and
efficiency by combining analytical formulations describing plastic hinge
behavior with empirical formulae based on experimental data. Several
empirical behavioral characteristics are implemented in this modeling
including (1) the variation of the tangent modulus of elasticity during
cycles, (2) the gradual plastification process of the plastic hinge, and
(3) the residual displacement due to material nonlinearities in the nominal
elastic range. Verification of the new model is performed on the basis of
quasi-static analyses of individual struts and dynamic response analyses of
a three-story X-braced steel frame, representative of offshore platforms.
The model is applied to the study of the design of a real sized six-story
K-braced steel building frame.

Base isolation, an approach to seismic structural design, is discussed,
and its use in the design of the Foothill communities Law & Justice Center
(FCLJC) in Rancho Cucamonga, California, is described. FCLJC's design
parameters are noted: it was designed for an 8.3 Richter event on the San
Andreas Fault, with all structural members remaining in the elastic range
and all functions remaining operational after the event. Additionally,
because all the significant earthquake motion is concentrated at the
bearings rather than encompassing hundreds of columns, beams, and walls,
the overall system is more predictable. The base-isolated design resulted
in a savings of $1 million in structural steel in comparison with the
conventional steel frame that had been employed in a preliminary design.
Finally, when compared to the preliminary design, the base isolated design
exhibited a reduction of forces transmitted into the building by a factor
of up to seven. Construction details are supplied, and appendices contain a
technical report on design of bearings, computer plots from time history
analyses, construction costs, fabrication descriptions, and a draft of the

A US Nuclear Regulatory Commission-funded experimental program designed
to obtain information on the structural behavior of reinforced-concrete
buildings has been underway at the Los Alamos National Laboratory since
1980. This information will aid the NRC in evaluating the seismic
capacities of existing Seismic Category I buildings. Scale models of
reinforced-concrete shear walls and buildings were subjected to static and
dynamic tests. Simulated seismic tests were conducted on model structures
constructed to two scales (1/30 and 1/10), permitting an evaluation of the
effect of scale in experimental investigations of reinforced-concrete
structures. Monotonic and cyclic quasistatic tests provide information on
strength, stiffness, strength and stiffness degradation, ductility, and
general load-deflection behavior up to the ultimate load. The dynamic tests
yielded information on natural frequencies, equivalent viscous damping
values, initial stiffness and stiffness degradation, and general response
behavior. These experimental investigations have indicated that sine-sweep
tests are not suitable for reinforced-concrete structures and that the
initial stiffness of shear wall structures is less than predicted when
assuming an uncracked concrete section. (ERA citation 09:040911)

The fracture mechanics approach was applied to evaluate the structural
integrity of 9% nickel steel tanks. An analysis was made of the side-wall
and bottom plate constructions, each with a welded joint, and the side-wall
to annular plate connection. The stress intensity factor (K) was calculated
for each structural component under the most conceivably severe stress
states coupled with the effects of probable seismic loads, assuming a
surface defect of 100 mm in a 1/5 plate-thickness, and compared with the
fracture toughness of appropriate welded joints determined from a number of
notched wide-plate tests. Fracture tests were also carried out on models
representing each structural component to confirm the predictions obtained
from K-value analysis. These results showed that 9% nickel steel tanks
provide sufficient safety margins in terms of brittle fracture under
emergency loads such as in the LNG containers.

Floor response spectra are commonly used as seismic inputs for the design
of secondary systems. Here several direct approaches based on the method of
mode displacement as well as mode acceleration have been developed for
generation of floor spectra for classically and non-classically damped
systems. The mode displacement approaches require pseudo acceleration and
relative velocity spectra whereas the mode acceleration approaches require
relative acceleration and velocity spectra as their seismic inputs. These
proposed approaches have been validated by a comprehensive numerical
simulation study involving several ensembles of time histories. For
structural systems with dominant high frequency modes, the mode
displacement approaches may give inaccurate results if only a first few
modes are used in the analysis, whereas the mode acceleration approaches
will still predict the response accurately. Therefore, the mode
acceleration approaches are proposed as better alternatives to the mode
displacement approaches which are currently used.

Results are presented of research on unreinforced masonry (URM)
buildings. An extensive survey of URM buildings in six regions of the
country was undertaken to identify the characteristics of those buildings.
A computer model was developed to pretest and predict the responses of
walls and diaphragms when subjected to simulated ground motion. Tests were
conducted on specimen walls and diaphragms and on existing URM buildings to
confirm and refine the methodology. A cost effective means was found for
evaluating and retrofitting URM buildings to withstand earthquakes. Use of
this innovation occurred as a result of important events during the life of
the research project, including a series of workshops held for officials,
engineers, and building owners to acquaint them with the research, and
active dissemination of project results.

Recent years have witnessed an intensified interest in the mechanics of
soils and rocks, as well as concrete. Applications in geotechnical and
structural engineering, mining and pretroleum engineering, nuclear power
plant safety, underground excavation, earthquake predictions, structures in
the ocean, and the mechanics of celestial bodies, abound with mechanics
problems which call for more realistic and.more accurate solutions. Work in
this field has proceeded to a large extent separately within various
professional groupst and communication among civil engineers,
geophysicists, mining engineers and theoretical mechanicists have been
quite limited, even though their problems are similar from the viewpoint of
mechanics. Therefore, the primary objective of the William Prager Symposium
was to bring together specialists from these various professional groups
and disciplines, and thus promote interdisciplinary cooperation.

The seismic response of steel composite curved box girder bridges has
been predicted by computing the natural frequency of the bridge and using a
response spectrum curve for both translation and rotational accelerations.

The natural frequencies have been predicted by simulation of the continuous
curved bridge, restrained by equivalent springs. These natural frequencies
are then utilized in conjunction with the response spectrum curves to
evaluate the equivalent seismic force to be applied to the structure.

An element of the seismic hazard assessment program at the Savannah River
Plant (SRP), South Carolina, was the measurement of the in situ
state-of-stress existing in the crystalline basement rock below the site.
Hydraulic fracturing stress and related geophysical measurements including
borehole televiewer logs were performed in a series of wells at various
locations on the SRP site. Prior to the start of the field program, scoping
studies using laboratory measured rock properties and the estimated
regional stresses in a boundary element program were performed to predict
if wellbore breakouts would occur in the borings depth. At the depths of
the wells, the laboratory strength of the rock was great enough to prevent
failure unless the in situ stresses were very high. The in situ stress
field measured at the site is similar to that found at comparable depths in
the region, where S(sub H) > S(sub h) > S(sub v) and the maximum horizontal
stress is oriented NE-SW. The measu 'red stress state indicated high
horizontal stresses that could cause rev-erse faulting on favorably oriented
pre-existing planes of weakness. Thisreverse faulting is consistent with
the observed structure of the basement rock on site. 22 refs., 5 figs., 2

Since hypocenters of earthquakes are usually deeper than those of
explosions, depth of focus measurement could be a valuable source
discrimination parameter for test ban treaty verification. In this paper,
we study the problem of determining depth of underground sources using a
small planar network. By deriving analytical results and by verifying these
results with computer simulation of seismic networks, we show that in terms
of estimating source depths accurately, performance of a network can be
improved using an appropriate distribution of stations. While it is
desirable to place the stations close to the source, there might be
physical limitations to this strategy in a verification scenario. We have
shown for a given closest station-source radial distance, it is desirable
to place some of the other stations about twice as far as this distance,
from the source, for better depth estimation. Furthermore, a distribution
of stations which results in a set of source-receiver distances which are
all different from each other is desirable for accurate depth estimation of
shallow sources. 10 refs., 6 figs. (ERA citation 14:027056)

For an accurate geoacoustic model to be constructed an area's geology
must be well understood. In some areas modeling may not be successful
because small-scale lithologic and topographic changes are not recognized
from available data. Currently, we cannot obtain complete measurements of
sediment properties such as velocity and density from a drill hole.
Laboratory and in situ measurements do not agree, and attempts to reconcile
the two have not been effective. In constructing our geoacoustic models we
added high-velocity stringers which are almost always present in nature;
e.g., worldwide occurrences of chert have been documented by DSDP cores. We
constructed geoacoustic models for 5 areas in the western North Atlantic.
For 2 areas we used laboratory and seismic data collected during DSDP
studies, as well as published reports, to construct detailed models. For
the remaining areas we tabulated generalized sediment velocity and
lithology information from published reports. It became apparent that some
11.5 @_Z
1%@

areas have such rugged topography and variable lithology that traditional
modeling probably will be unsuccessful unless the geology is known in great
detail. Some continental margin shallow-water sites and some deep ocean
sites, such as DSDP site 417/418, are much more predictable and should be
easier to model; however, even site 417/418 has unique geologic factors
that will cause actual seismic propagation to differ from our model
predictions. However, deviations from predicted values should be reasonably
small at (5-50 Hz) frequencies. (EDC)

A regional event discriminant is being developed and tested based on the
waveform of high frequency Pn. The data base being used in the development
consists of signals from explosions and earthquakes recorded on the western
U.S. digital network. It has been discovered that at most stations the
waveform of Pn onset is remarkably stable and different from the
corresponding waveforms from earthquakes. A forward modeling study of broad
band explosion PnIs revealed that the distinctive character of their
waveform is caused by a strong pPn arrival. Depth phases from earthquakes
arrive much later in the signal. It was found that a clear effective pPn
arrival was present in all cases. However, it consistently arrives later
than the predicted elastic time. For Pahute events, the amplitude of
effective pP is close to the elastic predictions. For Yucca Valley, it is
consistently larger indicating the effect of a site dependent nonlinear
process in the source region. An appropriate value of t* for Pn appears to
be in the range of 0.1 to 0.2 seconds. The frequency content of the
explosion Pn energy indicates that it is caused by turning rays in the lid
gradient rather than true head waves traveling on the crust mantle
interface. The discrimination capacity of the Pn waveform was measured
quantitatively by correlating the average explosion Pn trace with a data
base of explosion and earthquake signals. Keywords: Synthetic seismograms,

A particularly detailed. set of observations in the vicinity of an
intraplate, thrust earthquake (M 7.4) in Argentina, indicate a cyclic
pattern of deformation very similar to that reported previously for
interplate earthquakes. This deformation cycle, which may be characteristic
of many seismically active areas, consists of: (1) steady strain
accumulation, possibly punctuated by strain reversals; (2) coseismic strain
release; (3) a period of continued strain release due to afterslip
(persisting for perhaps a year or so); and (4) rapid postseismic strain
accumulation which decreases exponentially and grades into steady strain
accumulation. Deformation associated with three earthquakes in the U.S.
(1940, M7.1 Imperial Valley California; 1964, M8.4 Alaska; 1959, M7.5
Hebgen Lake, Montana) are interpreted in light of this general earthquake
cycle and are used to investigate the mechanics of strain release for these
events. These examples indicate that large postseismic movements can occur
for strike-slip, thrust, and normal fault events, and both viscoelastic
relaxation and postseismic after-slip must be incorporated in models of
earthquake related deformation. The mechanics of the strain release process
revealed by these examples has implications for estimating earthquake
repeat times from geodetic observations near active faults.

The overall objective of this research is to stimulate the development of
wave propagation sensor techniques for the evaluation of in-situ
conditions. Assessment of conditions in the built environments is critical
to the management of infrastructure, and there are significant
opportunities for developing such sensor technology which have yet to be
fully exploited. This research has been directed towards providing a
development framework, and an associated set of developmental tools,
applicable to wave propagation techniques. Such techniques include
seismics, sonics and ultrasonics, and impulse radar. The research has
focused on the development of tools in two areas: (1) predictive analytic
models and waveform synthesis techniques, and (2) laboratory evaluation
techniques. The development of these tools has been specifically oriented
towards applications involving identification, location, and
characterization of regular and irregular subsurface anomalies. originally
this research was conceived in an effort to exploit commonalities between
electromagnetic and mechanical wave propagation techniques. As we discussed
in the summary of findings, this perspective was found to be too broad at
this stage of the research. Such a perspective will be more meaningful when
a better understanding of specific properties of the media is achieved.

This report presents a preliminary assessment of the costs and benefits
associated with changes in the seismic design basis of waste-handling
facilities. The objectives of the study are to understand the capability of
the current seismic design of the waste-handling facilities to mitigate
seismic hazards, evaluate how different design levels and design measures
might be used toward mitigating seismic hazards, assess the costs and
benefits of alternative seismic design levels, and develop recommendations
for possible modifications to the seismic design basis. This preliminary
assessment is based primarily on expert judgment solicited in an
interdisciplinary workshop environment. The estimated costs for individual

attributes and the assumptions underlying these cost estimates (seismic
hazard levels, fragilities, radioactive-release scenarios, etc.) are
subject to large uncertainties, which are generally identified but not
treated explicitly in this preliminary analysis. The major conclusions of
the report do not appear to be very sensitive to these uncertainties. 41

The Navy has $25 billion worth of facilities in seismically active
regions. Each year $200 million of new facilities are added to those in
seismically active areas. The Navy, because of its mission, must locate at
the waterfront with a high watertable and often on marginal land.
Seismically induced liquefaction is a major threat to the Navy. Presently,
procedures do not exist to analyze the effect of liquefaction on
structures. Developing an effective stress soil model will provide a tool
for such analysis of waterfront structures. To understand the significance
of liquefaction, it is important to note the damage caused in recent
experiences. This study is directed toward examining the predictive
capabilities of the numerical procedure proposed in a previous work titled
studies of the capabilities of a soil model to predict axial

A mathematical model to describe seismic wave propagation in both dry and
water-saturated, particulate materials is derived on the basis of the
response of a regular array of like elastic spheres. The theories of Hertz
and Mindlin are used to model the normal and tangential compliances at the
intergranular contacts and the overall response of the array is found to be
governed by a set of nonlinear equations that depend on the quasistatic
loading history. These equations are integrated over a particular stress
history that simulates the normal buildup and relief of geostatic stress
(overburden pressure) in nature. Wave velocities are evaluated at various
stages during this stress history and the response is found to be
anisotropic with respect to both p- and s-wave velocities. In order to
simulate the response of marine sediments, the effects of water saturation
are investigated by using the compliances calculated for the dry skeletal
frame in conjunction with the Biot theory. Predictions of the model were
compared with laboratory experiments and all the general trends in response
were found to agree. Reprints. (EDC)

We have made significant progress in the past two years towards our goal
of understanding fundamental processes of subduction. The results range in
spatial dimensions from small scale details of the plate interface within
the Shumagin seismic gap to updated probabilities of the occurrence of
great earthquakes along the entire Aleutian arc, and in time from the
earliest instrumentally recorded earthquakes to automatic processing of the
most recent events. It is necessary to study the entire range of scale
lengths because of the interaction between different tectonic elements. A
simple kinematic model describing flow of material down the Aleutian
subduction zone shows that arc geometry and current convergent directions
and rates can explain the distribution of seismicity and volcanism along

the arc. Studies of the seismic source have begun to expand the frequency
band over which seismic rupture can be analyzed. A comparison of short and
long-period data from the Andreanoff Island earthquake raises fundamental
questions about how decoupled in space and time can the radiation of high
frequency energy be from the release of moment-rate producing slip during a
dynamic rupture. The basic source parameters were modeled by inverting
long-period P and SH waves while the high frequency characteristics were
approximated by the superposition of many small earthquakes used as
empirical Green's functions. Modeling of the earthquake source has also
added insight into the mechanics of the transition from subduction zone to
transform fault in the Gulf of Alaska region. 34 refs., 19 figs. (ERA

The purpose of this project, initiated by INTEVEP is to develop a seismic
hazard characterization for the region of the Lake Maracaibo basin in
Western Venezuela (WV) with an emphasis at the sites of dikes built on the
eastern side of the lake. one task of the project was to assess the
seismicity of this region and to describe it in a form which can be used as
input to a seismic hazard analysis. The seismic parameters of interests
were seismo-tectonic zonation, distribution of earthquake magnitudes, and
the largest earthquake, i.e., upper magnitude cutoff. Because it is
difficult, or perhaps impossible, to precisely quantify such seismic
parameters using only the sparse historical record, expert judgment is
crucial. Thus two panels of experts were assembled, to supplement the lack
of opinions in the possible models of zonation, seismicity, (S-panel) and
ground motion attenuation (G-panel). In addition to the ground motion
models described in the ground motion questionnaire handed to the G-panel
experts, we performed some analysis, at LLNL, to develop a new breed of
models where the parameter of interest is now the number of cycles of a
given fraction of the peak ground acceleration, as a function of magnitude
and distance from the source of an earthquake, rather than the peak ground
acceleration (PGA) as a function of magnitude and distance. 20 refs. (ERA

An airblast prediction program for explosions, called BLASTO, has been
written for use with IBM-PC (or compatible) computers, to produce
overpressure-distance curves for a variety of interactive input conditions.
Several common units are allowed for each input, but calculation and output
are in SAI metric units. Explosion yield (chemical or nuclear) and ambient
atmospheric pressure are used to generate a referenced 'Standard'
overpressure-distance curve. Explosives may be point charges at any height,
above ground or depth below the earth surface. Buried charges may also be
distributed in a sheet, or 1HEST1 configuration. If upper air weather data
or forecasts are available, they can be used to generate directed (wind
effects) sound velocity versus height structures which are interpreted to
give attenuated or enhanced overpressure-distance curves. These are
calculated for directions around the compass or toward specified targets or
communities. Evaluation of the recent accidental explosion at an ammonium
perchlorate (A-P) plant in Henderson, Nevada, made use of BLASTO. Damage
inspection gave some estimates for incident overpressure at various ranges.
These showed considerable scatter, but they generally surrounded an
overpressure versus distance curve calculated for 1-kt NE free-air burst.
Weather data and directed sound velocity calculations showed that some of
the closest residential damages were in directions of minimal
weather-dependent blast distortion, allowing the conclusion that the
largest explosion could be simulated by a 250-ton HE surface burst.
Video-camera recordings, newspaper eye-witness accounts, post-accident
aerial photographs, seismic recordings, and a report of the A-P storage
pattern have been reviewed to show that this largest blast probably
occurred in a 1500-ton A-P collection. This leads to 1:6 TNT airblast
equivalence for A-P. 15 refs., 9 figs. (ERA citation 13:049473)

Several studies of seismic hazards and seismic risk have been done for
the Los Alamos area. The most comprehensive one was completed in 1972 and
was intended for design engineering for the TA-55 Plutonium Facility. This
6@@

study concluded that a peak horizontal acceleration of 0.33 g was
appropriate for design of facilities at TA-55 since it was "unlikely to be
exceeded." Progress in several areas of earthquake studies in the past 15
years has provided an improved understanding of earthquake occurrence and
recurrence, as well as an improved ability to estimate ground response
resulting from possible local earthquakes. Because the results of the 1972
study are still being used for seismic design of new facilities at Los
Alamos, the seismic hazards and risks for Los Alamos should be reevaluated
in order to confirm that the 1972 results are still meaningful and valid.
Such a reevaluation is, however, beyond the scope of this report. 49 refs.,

The US Department of Energy proposes to develop a limited enhanced oil
recovery project in the Shallow Oil Zone at Naval Petroleum Reserve No. 1
(NPR-1) Elk Hills. The project would employ steam forced into the
oil-bearing formation through injector wells, and would involve two phases.
The initiation of the second phase would be dependent on the economic
success of the first phase. The total project would require the drilling of
22 new wells in a 45-acre area supporting seven existing production wells.
It would also require construction of various surface facilities including
a tank setting (gas-oil separation system), steam generators, and a water
treatment plant. Adverse environmental impacts associated with the proposed
steam flood project would include the effects on vegetation, wildlife and
land-use resulting from the total reconfiguration of the topography within
the project bondaries. Other adverse impacts include the emission of oxides
of nitrogen, carbon monoxide, hydrocarbons and particulates from steam
generators, vehicles and associated surface facilities. Minor adverse
impacts include localized noise and dust during constuction, and reduction
of visual quality. 48 refs., 7 figs., 10 tabs.

Los Alamos lies along and upon the Pajarito fault system, a major
intragraben structure of the Rio Grande rift. This fault system consists of
over 100 km of interconnected fault zones and traces. Geomorphic evidence,
including righ-lateral steps in stream valleys and disrupted drainages, as
well' as apparent vertical offset of alluvial units determined by seismic
refraction, strongly suggests that the Pajarito fault zone is active. To
evaluate seismic hazards in the Los Alamos area, values for recurrence
intervals and characteristic earthquakes of the faults must be determined.
We recommend the trenching of young alluvium in Rendija and Guaje canyons
to obtain information regarding recurrence of the characteristic
earthquake. 23 refs., 9 figs. (ERA citation 13:031094)

The aim of this research is to valid the geoprospective approach
elaborated previously in the framework of contracts with Commission of
European communities. The geoprospective approach is applied to a
"paleosite" i.e. to a region the evolution of which can be reconstructed
for the last 100.000 years. This work is performed on a part of Parisian
Basin near the English Channel coast. It allows to simulate the combined
effects of sea and river level variations, and tectonic activity. All these
factors taken in a rather severe context, would not have changed
significantly, the confining conditions of the geological barrier around a
radioactive waste repository. (ERA citation 13:008568)

Peculiar stress anomalies in the descending slab have been documented by
composite focal mechanisms to be associated with the zone that in 1978-80
slipped aseismically at depth. The exact geometry of the descending slab
has been delineated with the help of three-dimensional ray tracing. The
detailed seismicity, tectonics and seismic potential of the Unalaska
seismic gap have been reviewed. It is believed to be presently capable of a
Mw approx. = 8.6 earthquake. A thorough analysis of the volcano seismicity
of Pavlof volcano indicates a close correlation of seismic signals with
periods prior and during eruptions, probably related to degassing of mobile
magma in the upper 1.6 km of the volcanic vent. After some quiescence in
1985 Pavlof erupted vehemently in spring 1986 a nd is still active at
present. A strong (10%) low-velocity anomaly in the crust beneath Pavlof
volcano and Emmons caldera has been detected. Strong-motion data for most
of Alaska, including those collected by the Shumagin accelerometer array
have been analyzed and indicate high peak accelerations and large scatter.
A thorough review of the seismic and volcanic hazards in the Gulf of Alaska
has been completed. Research results for the period 1984 to 1986 were

As part of continuing program to investigate the characteristics of
acoustic propagation and ambient noise in the very low frequency regime (20
Hz and less). Ninety -seven experiments were conducted off the Southeastern
coast of the U.S. (Cape Fear) in 1985. Preliminary results of the Cape Fear
data analysis have already shed some light on seismo-acoustic propagation.
At the source-receiver ranges thus far considered, considerable penetration
into the bottom is evident, particularly at frequencies below about 20 Hz.
Both body and Scholte waves appear to contribute to the propagation in the
sediment. Under certain conditions, the net SIN ratio of the vertical
geophone sensor is at least 6 dB higher than that of the hydrophone.
Although examination of the depth dependence of the waterborne transmission
loss as a function of range is still in process, spot checks at several
ranges do indicate agreement between the model (IFDPE) and measured results
(hydrophone array). The SAFARI and IFDPE models provide some insight into
certain aspects of the propagation, but alone, neither is sufficient for
the environment considered. It is expected that models based on the finite
difference method will be more appropriate.

Short-period (SP) seismograms are much better than long-period (LP)
seismograms to get the time resolution needed for the focal-depth
estimation. However, complex scattering effects due to crustal
inhomogeneities and also the multi-pathing of signals usually complicate
the short period records. On the other hand, the seismograms from
long-period signals demonstrate clear coherent body waves. Therefore, for
intermediate depths (15-60 km) prediction error filtering of LP signals
will be useful for identifying the depth phases. Such a study was carried
out in the first part of this report. In a group of 7 events, the p/sup p/
phases were extracted from LP signals and the depths so estimated compared
well with the published data. For explosions at shallow depths (depth < 10
km), one expects that P and p/sup p/ phases will tend to cancel each other
in LP seismograms. As the source depth increases, the cancellation becomes
less effective. This feature can be used for the identification of an event
as well as for getting an estimate of the source depth. This phenomenon can
be successfully exploited for identifying multiple explosions, because at
teleseismic distances ( delta > 30/sup o/) no LP (around 20s period) P
waves will be seen in the seismogram due to such events whereas relatlvFl
ly

strong SP signals and LP Rayleigh waves will be observed. This phenomenon
was studied for 16 events. For three of these events having m/sub b/ as
high as 6.1 and presumed to be underground explosions, one could not see
any P wave on remaining 13 events (which were classified as earthquakes),
it was possible to set a threshold value of m/sub b/ above which an
earthquake should produce LP P-wave signals at a given distance. 8

For detecting the depth phases, a parametric model for P signal was
adopted. In other words, the primary P pulse is characterised by numerical
values of 6 few parameters (usually 10-20). As the reflected P phase will
be almost identical to the P phase, the same model will be valid for such
phases also. For seismic signals, a special type of parametric model called
autoregressive (AR) model is found useful. It is shown that the prediction
error filter (PEF) for a given order as computer by AR model of the time
series is same for the primary P phase as well as for the composite wave
comprising 'the primary P phase and several reflected and refracted phases.
Therefore, when the composite wave is convolved with its PEF, there will be
large local errors around the instants when the reflected or refracted
phases start entering the seismogram, thereby facilitating the
identification of such phases. It is shown that using any order of the PEF,
not necessarily the optimum, the depth phases can be extracted from the
seismograms. However, in order to detect the depth phases unambiguously,
the delay time of the depth phases w.r.t. the P phase should be greater
than or equal to 0.3s. The method could unambiguously detect the depth
phases from the signals having signal-to-noise ratio greater than or equal
to 4. For weaker signals, array beams may be used to extract the depth
phases. It was also demonstrated that T/sup */ (travel time to quality
factor ratio)= 0.6s tends to give better results than T/sup 1.0s. 40

Tide gauges can be used in registering vertical movements of the land and
also afford possibilities for predicting earthquakes, although much
additional work must be done to realize these possibilities. The
oceanographic method already makes it possible to detect anomalies in
vertical movements of the land of not less than 1-2 cm. An expression has
been derived for computing the effective radius of the method. The method
can be used in predicting relatively close earthquakes and could probably
be effective in predicting earthquakes with M greater than or = 7.0 if the
distance between level stations does not exceed 80 km. It is highly
important that the observation points be situated as close as possible to
the epicentral zone of an anticipated earthquake. Bottom pressure sensors
are now. available which can measure ocean level distant from its shores
with a high degree of accuracy, thereby making it possible to study
vertical movements of both the land and ocean floor, in the latter case
inaccessible for other observation methods. It is probably possible to
detect earthquake precursors in this way. In the Far Eastern region
especially, the use of bottom pressure detectors may become an effective
method for predicting earthquakes.

A high-level-waste repository located in unsaturated welded tuff at Yucca
Mountain, Nevada, would rely on six different, although not entirely
independent, barriers to prevent escape of radioactivity. These barriers
are the waste canister, fuel cladding, dissolution of the spent fuel
itself, and movement of released contaminants in the unsaturated Topopah
Spring welded tuff unit, the unsaturated Calico Hills nonwelded tuff unit,
and the saturated tuff aquifer. Fifty-eight processes and events that might
affect such a repository were examined. Eighty-four different sequences
were identified by which these processes and events could lead to failure
of one or more barriers. Sequences that had similar consequences were
grouped into 17 categories: direct release, repository flooding, colloid
formation, increased water flux through the repository, accelerated
fracture flow, water diverted toward the waste package, accelerated
dissolution mechanisms, accelerated cladding corrosion mechanisms,
accelerated canister corrosion mechanisms, canister breakage, fracture flow
in the,,Topopah Spring welded unit without increased moisture flux, reduced
sorption in the Topopah Spring welded unit, water table rise above the
Calico Hills nonwelded -unit, fracture flow in the Calico Hills nonwelded
unit, new discharge points, and faster flow in the saturated zone. 52

Prediction error filtering has been found very useful for the
identification of the depth phases corresponding to weak and shallow
events. Its applicability can be further improved provided the ambient
seismic noise is reduced by some means. A parametric model based on
autoregressive (AR) method has been shown to be suitable for this purpose.
In this method, the noise preceding the signal is modelled as an AR
process. The time series comprising pre-event noise and the composite
waveform consisting of P and the P/sup P/ phases is filtered using the
above AR model. Due to this filtering, the original time series is changed

into a new time series. Though the P signal structure changes, the
structure of the reflected or the depth phase also changes the same way.
The spectrum of the new modified signal will be close to S(w)/N(w), where
S(w) is the P wave spectrum and N(w) is the spectrum corresponding to the
preceding noise in the original time series. The modified signal will have
predominant amplitudes around the frequencies w, for which S(w) happens to
be large compared to N(w). However, the new time series will be
contaminated with a band limited white noise series. By appropriate digital
filtering of the new time series and after remodelling the filtered time
series using AR method, it has been shown that the onsets of the depth
phases from very weak signals can be successfully extracted. A signal
having signal to noise ratio (SNR) of 2 or more can be successfully
subjected to this method for locating the onsets of the depth phases. For
even weaker signals (SNR approx. = 1 ), one can subject the array beams to
this method for the extraction of the depth phases. 10 refs., 3 tables, 22

This report presents the applicability study of the prediction error
filtering for the identification of depth phases corresponding to some
presumed underground explosions in USSR region. For six events from eastern
Kazakh, USSR (EKZ) region, the data of Warramunga array (WRA) and
Gauribidanur array (GBA) have been analysed. The source depths as estimated
from GBA and WRA data were in good agreement. Apart from these six events,
a set of 23 events from various test sites in USSR as recorded in GBA were
subjected to prediction error filtering and in each case the depth phase
was identified. A time separation as small as 0.3s between P and the p/sup
p/ phase could be resolved successfully. Several weak presumed explosion
signals from USSR region were also analysed and a comparative study was
done for these weak events using prediction error filtering with and
without pre-filtering the noise. It was demonstrated that the pre-filtering
of noise improved the depth phase identification capability substantially
in case of weak signals. 39 figures, 9 refs. (Atomindex citation 18:095220)

The source parameters of 19 large earthquakes in the Gulf of California
were determined from inversions of long-period P and SH waveforms. The goal
was to understand the recent slip history of this dominantly transform
boundary between the Pacific and North American plates as well as the
effect on earthquake characteristics of the transition from young oceanic
to continental lithosphere. For the better recorded transform events, the
fault strike is resolved to + or - 4 deg at 90 percent confidence. The slip
vectors thus provide important constraints on the direction of relative
plate motion. Most centroid depths are poorly resolved because of tradeoffs
between depth and source time function. On the basis of waveform, modeling,
historical seismicity, and other factors, it is appropriate to divide the
Gulf into three distinct zones. The difference in seismic character among
the three zones is likely the result of differing levels of maturity of the
processes of rifting, generation of oceanic crust, and formation of stable
oceanic transform faults. The mechanism of an earthquake on the Tres Marias
Escarpment is characterized by thrust faulting and likely indicates the
direction of relative motion between the Rivera and North American plates.
This mechanism requires revision in plate velocity models which predict
strike slip motion at this location.

Engineering seismology is aimed, among others, at predicting a strong
reference motion for the site of a given critical structure to be used in
the design of said installation. A common practice, when modal analysis is
performed in view of the anti-seismic design of structures, is to use, as
the input motion, a set of spectra with progressive values of damping. Such
a practice is discussed. Parallel to those empirical predictions, attention
has been drawn on strong motion studies. Progress has been made in the
theoretical simulation of seismic sources and wave propagation. Reliability
of inverse problems relating to type of rocks is discussed. Attempts of
solutions are recalled. (ERA citation 12:048092)

An improved technique for detecting subsoil radon in the Ashkhabad
seismoactive zone in order to predict earthquakes in this region is
described. Radon alpha -particles were recorded with a nitrocellulose
detector. Chemical treatment was carried out in a 10% sodium hydroxide
solution at 60 deg C temperature, and detector scanning was performed using
an optical microscope and a spark counter. The optimal parameters of

stationary device for the irradiation of detectors in 70 cm deep pits have
been determined experimentally. The points of observation of temporal
variations of the radon have been chosen with the aid of emanation survey.
Constant radon measurements were carried out at three observation points
during the period from 1982 to 1983 at intervals of 5-7 days. The
dependence of track density on calendar time and on atmospheric conditions
has been found to be regular. A broken regularity may be due to the K
greater than or equal to 10 energy class seismic event which took place in
this region at a distance of 100-130 km from the observation point. 14

forecasting. Biologists have accumulated extensive experimental data on the
impact of various electromagnetic fields, including fields of weak

Earthquakes continue to be a terrible threat to humankind. scientists
often fail to predict them and protection against them is often
ineffective. The reason for this is the inadequate knowledge of the
formation and operation of sources of disastrous tremors known as seismic
foci. How seismic foci can be used to forecast earthquakes is discussed
along with different methods to study them.

The maximum shear stress (mss) field due to mass anomalies is estimated
in the Apennines, the Kermadec-Tonga Trench, and the Rio Grande Rift areas
and the results for each area are compared to observed seismicity. A
maximum mss of 420 bar was calculated in the Kermadec-Tonga Trench region
at a depth of 28 km. Two additional zones with more than 300 bar mss were
also observed in the Kermadec-Tonga Trench study. Comparison of the
calculated mss field with the observed seismicity in the Kermadec-Tonga
(f5)

showed two zones of well correlated activity. The Rio Grande Rift results
showed a maximum mss of 700 bar occurring east of the rift and at a depth
of 6 km. Recorded seismicity in the region was primarily constrained to a
depth of approximately 5 km, correlating well to the results of the stress
calculations. Two areas of high mss are found in the Apennine region: 120
bar at a depth of 55 km, and 149 bar at the surface. Seismic events
observed in the Apennine area compare favorably with the mss field
calculated, exhibiting two zones of activity. The case of loading by
seamounts and icecaps are also simulated. Results for this study show that
the mss reaches a maximum of about 1/3 that of the applied surface stress
for both cases, and is located at a depth related to the diameter of the
surface mass anomaly.

The USGS has been assisting the DOE in evaluating the suitability of the
Yucca Mountain area, located on and adjacent to the Nevada Test Site (NTS)
and about 160 km northwest of Las Vegas, as a possible repository site for
the disposal of commercially generated high-level radioactive wastes and
wastes from DOE facilities. An essential part of this work is defining the
geology and hydrology of the area in order to assess the potential for the
transport of radionuclides from a repository to the human environment. In
addition, the potential for disruption of a repository as a result of
volcanic or tectonic activity or accelerated erosion is being evaluated. As
part of the Nevada Nuclear Waste Storage Investigations (NNWSI) project,
the USGS is performing multi-disciplinary studies involving detailed
surface mapping, surface geophysics, exploratory drilling, borehole
geophysics, and topical studies of hydrology, climate, and tectonics.
Studies are being performed to assess the potential for faulting, damaging
earthquakes, recurrence of volcanism, and local acceleration of erosion in
parts of the southern Great Basin. Hydrologic investigations are directed
to determination of present and past hydrologic regimes of the NTS and
vicinity in order to predict the potential for ground-water transport of
radioactive waste from a repository in Yucca Mountain to the accessible
environment. Paleoclimatic studies are also being performed to aid in
predicting future climate in the NTS vicinity. (ERA citation 12:032529)

In the Long Valley caldera, an area of recently (approx.550 y) active
volcanism and current seismic activity, sup 222 Rn concentrations in hot,
warm and cold spring waters have been measured since 1982. Rn contents of
the waters correlate inversely with temperature and specific conductance,
with high concentrations (1500 to 2500 pCi/1) occurring in dilute cold
springs on the margins of the caldera, and low concentrations (12 to 25
pCi/1) in hot to, boiling springs. Rn correlates only slightly with the
uranium contents of the wide range of rocks which host the hydrological
system feeding the springs. These environmental effects on the radon record
may mask responses to small or distant seismic, volcanic, or crustal
deformation events. To date, anomalous changes in water-borne Rn have been
observed An connection with at least one earthquake, which occurred close
to the monitoring site. This continuing study points out that an
understanding of the geological setting, its associated hydrological
system, and environmental influences is necessary to properly evaluate
concentrations and changes in groundwater radioactivity. (ERA citation

Within the frame of a contract with the CEC, dealing with storage and
disposal of radioactive wastes in geological formations, the BRGM has been
involved in a research on prospective tectonics. Within the Western
European continental plate, since Mesozoic times, one sees the alternation
or succession of convergent and divergent tectonic episodes. These tectonic
episodes, although representing geologically discontin 'uous phenomena, still
have time periods of between 4 to 40 millions years. These tectonic
phenomena are the cause of the formation or reactivation, at all scales in
the continental plate, of brittle, fault-like structures. Tectonic analysis
and the in situ measures of stress and the earthquake focal phenomena show
that, from the lower Quaternary to the present, the Western European
continental plate has been subjected to NNW to SSE convergent stress. A
study of the arrangement of European and African plates in the Western
Mediterranean shows that the entire region, is undergoing a period of
continental collision. The change in the process implies a westerly
continental drift of the Spanish plate, a movement which would take several
million years. On the Western European scale, the most likely hypothesis
during the next 100,000 years is the persistance of the present stress
trending approximately N-5. On the other hand, on a local scale,
reorganisations of this stress are possible, owing to the presence of
tectonic or lithological heterogeneities. (ERA citation 12:022270)

The 100- and 500-year combined tsunami and tide elevations were predicted
at sites along the coast of Alaska between Kodiak Island and Ketchikan.
Lack of historical data at most sites necessitated the generation of a
synthetic record of tsunami activity in the Gulf of Alaska. The geophysical
and tectonic setting of the Gulf were used to synthesize a record of
tsuamigenic, tectonic deformations of the seafloor. A numerical model was
used to simulate the tsunamis resulting from each deformation. Numerical
simulations of the 1964 Alaskan tsunami were made and compared with
historical tide gage recordings. Historical data of tsunami activity along
the entire Aleutian trench were used to assign probability of occurence to
each tsunami in the synthetic record. A numerical procedure was used to
combine the effects of astronomical tides and tsunamis and to produce to
100- and 500-year combined tsunami and tide elevations. (Author)

This report is concerned with an empirical study so the response spectra
of western United States earthquakes, principally in California. The basic
data are logarithms of response spectral velocity as a function of period.
They are the arithmetic average of the logarithm of the response spectral
values for the two horizontal components of motion for 5 percent damping.
The anelastic attention id determined empirically from the response
spectra. It satisfies the relation Q(f) = 150 times f to the 0.6 power,
where Q(f) is the specific quality factor at a frequency of f. The
coefficient of anelastic attenuation k(f) is related to Q(f) by k(f) = pi
times f/v Q(f), where V is the velocity of the wave. Observed response
t .61

spectra are extrapolated to a reference distance of 50 km for earthquakes
of different magnitude. From these spectra a scaling relation is
determined, which is expressed in the form of a set of equations. These
equations enable one to predict response spectra for any body-wave
magnitude for distances greater than 50 km. The predicted values agree well
with observed ones at distances greater than 50 km, but show more
variations at distance less than 50 km.

To support the on-going research on Solar Oscillations and Convective
Flows as Probes of Structure in the Subphotosphere, a vector array
processor system was acquired to augment the existing DEC VAX-11/750
computer system. The fifty-fold average increase in computing speed offered
by the array processor would make it feasible to invert solar oscillation
data on a regular basis, and thereby permit us to use the five-minutes
oscillations of the Sun to probe the turbulent convection zone below the
surface of this star. The array processor would also permit us to carry out
detailed numerical experiments with compressible convection in the presence
of magnetic fields, for the speed and memory of the machine makes it a
formidable tool for direct numerical simulations of two- and
three-dimensional fluid dynamics. Such theoretical simulations are also
needed to study the solar dynamo and its ability to build and transform
magnetic fields, an issue central to solar-terrestrial variablility and
predictions of solar activity. Attached as Appendix A is a cover article in
Science Magazine that describes the importance of the work on the
Seismology of the Sun that is beginning to emerge from the class of array
processors.

Several earthquake recordings at Golden, Colorado in the magnitude ranges
4-6, were digitized and were used to investigate the feasibility of adding
them together to simulate a larger earthquake (magnitude 7.0-7.5). The test
path of the Wasatch Front, Utah, to the WWSSN station at Golden was
selected (distance = 400 - 500 km). The hypothetical causative fault was
given dimensions on the order of 45 km long by 20 km wide and was divided
into 'cells,' representative in size to the 'seed' events rupture
dimensions and with other variations. The results were evaluated by total
energy and amplitude criteria. The final waveforms were judged to be
adequate predictions at the lower frequency end of the spectra. The high
frequency content was controlled by the spectra of the seed earthquakes
whose magnitudes were too large to adequately reproduce the Green's
function response at these frequencies. It is recommended that this
technique be used at smaller distance ranges or at stations whose
sensitivity is set high enough so as to record the smaller magnitude
earthquakes, more representative of impulse responses at all frequencies.

This report discusses vertical airblast-induced ground motions produced
by nuclear explosions over a dry soil medium taken to model Frenchman Flat
of the Nevada Test Site (NTS). Material properties for use in first
principle calculations were synthesized from very limited dynamic
laboratory stress-strain data, various soil index characteristics, and
seismic data. Parametric calculations with a one-dimensional, plane-strain
finite difference code were used to define a theoretical simplified model
that expresses peak vertical particle velocities and displacements as a
CT57

function of yield, peak overpressure and depth. Ground motions predicted by
this model were then compared to ground motion data from nuclear explosions
in Frenchman Flat. In particular, predictions of the simplified model were
reasonably consistent with PRISCILLA data which were a primary basis of
empirical prediction procedures widely used in the design and analysis of
strategic structures during the past ten years. The theoretical model could
be altered (where little or no dynamic soil property data exist) to provide
even better agreement between calculated and measured ground motions.
Conversely, study of qualitative features of the theoretical results
provide insight into the basic wave propagation phenomena in Frenchman Flat
that could improve the interpretation of the experimental data such that a
more consistent comparison between theory and experiment may result.

In June 1985 a committee of the Board on Earth Sciences asked the
National Research Council/National Academy of Sciences to bring to the
attention of officials of the federal government the scientifically
endorsed recent prediction of a moderate earthquake at Parkfield,
California, between 1986 and 1993. The prediction offers a unique
opportunity to improve our understanding of earthquakes and our future
ability to predict them. An augmented experimental program at,Parkfield is
needed to document this high-probability event more completely, including
the detection of premonitory phenomena. The report contains the information
that was presented to government officials. It is intended to stimulate
their interest, understanding, and enthusiasm for augmenting an
experimental program. If successful, the Parkfield experiment will
eventually translate into decreasing the vulnerability of people to
earthquake hazards.

Stimulation data that were measured at the Department of Energy's (DOE)
Multi-well Experiment (MWX) are being analyzed with the Morgantown Energy
Technology Center's (METC's) hydraulic fracture models. The results of the
analysis will improve the stimulation technique efficiencies and the
predictive capabilities of hydraulic fracture models for low permeability
(tight) gas sandstones. Post-stimulation hydraulic fracture predictions
that are made with data from the MWX paludal zones 3 and 4 sandstone
formations are included in this report. Post-stimulation fracture
diagnostics, hydraulic fracture model predictions, and ongoing and future
model analyses are presented. Results from reservoir and hydraulic fracture
modeling have shown that complex induced fracture behavior exists in tight
gas formations. The hydraulic fracture models predict fracture geometries
similar to those that are derived from seismic mapping of the induced
fracture. However, disagreement between pressures recorded during the
treatment and the predicted pressures indicate that significant model
improvements are required to predict complex fracture behavior in tight
sandstone formations. Stimulation treatments scheduled for the MWX coastal
interval will provide additional data for western gas sands (WGS) model
analysis and development. 9 refs., 12 figs., 5 tabs. (ERA citation

This report provides a source of state-of-the-art information on tsunami
engineering. The report summarizes available information, identifies gaps

in existing knowledge, and discusses methods of predicting tsunami
flooding. The generating mechanisms of tsunamis and the method of
determining the probability of occurrence are given. Because of the limited
data available on tsunamis, numerical methods are commonly used to predict
tsunami flooding of coastal areas. Finite-difference equations are
presented for simulating the propagation of tsunamis, but computer programs
are omitted because of the continuing work in progress and the availability
of up-to-date computer programs from other sources. Known mathematical
solutions, for tsunamis approaching the shoreline and tsunami-shoreline
interaction, are given to illustrate the effects of tsunamis and provide
means of verifying numerical results. The report discusses
tsunami-structure interaction and illustrates various types of damage
caused by tsunamis. (Author)

Prediction of seismic coupling for nuclear monitoring requires
theoretical models capable of calculating ground motions. The models must
have a sound physical basis and be able to represent dynamic material
behavior near the source. This portion of the study of stress wave
propagation in low porosity rock is aimed at determining quasi -static
properties of rock necessary to use in numerical models predicting wave
propagation. Further, the failure proces 's of low porosity rock under
simulated shock loading is being studiled to establish the failure
mechanisms. Initial effort supported by the contract was devoted mainly to
obtaining and preparing samples of Westerly granite for experiments.
Preliminary experiments to characterize the properties of Westerly granite
were performed on small samples obtained from the Bonner Monument Co.
Material properties measured agreed well with previous determinations.
Deformation of Westerly Granite was measured under standard triaxial
loading conditions and under a loading path mimicing shock wave passage.
Unlike high porosity rocks, the different loading paths did not
substantially affect the strength of the low porosity granite. The failure
envelope determined in standard triaxial tests agreed well with that
measured under simulated shock loading.

This analysis of the potential public health impacts of M55 rocket
disposal considered normal operations (with no release) and postulate
accident for hypothetical incineration facilities at five CONUS M55 rocket
storage depots (Anniston Army Depot, Lexington-Blue Grass Depot Activity,
Pine Bluff Arsenal, Tooele Army Depot, and Umatilla Depot, Lexington
Activity) and at Johnston Island in the Pacific Ocean. It also considered
the Chemical Agent Munitions Disposal System (CAMDS) currently in operation
at Tooele Army Depot. For each case, the postulated accidents were a severe
earthquake that would result in the loss of containment of an agent holding
tank, releasing a large quantity of liquid agent GB ro VX to the
environment, and a fire stripping the carbon bed, releasing a smaller
quantity of agent to the environment. The analysis calculate downwind
hazard distances for each installation and accident considered using the
vapor-depletion version of the D2B atomospheric dispersion code of the U.S.
Army Chemical Research and Development Center, for accidents under
conservative most likely and worst-case meteorological conditions. This
code predicts distances to 50% lethality, 1% lethality, and no deaths. A
modified-box approach to atmospheric dispersion was used to identify
no-effects distances beyond 20 km for each accident scenario.
Populations-at-risk and lethalities were calculated for each release
scenario, based on the agent source strength, downwind hazard distances,
and populations surrounding the subject depots. Keywords: Alabama;

This study is an assessment of the ground shock which may be generated in
the event of an accidental explosion at J5 or the proposed Large Altitude
Rocket Cell (LARC) at the Arnold Engineering Development Center (AEDC). The
assessment is accomplished by reviewing existing empirical relationships
predicting ground motion from ground shock. These relationships are
compared with data for surface explosions at sites with similar geology and
with yields similar to expected conditions at AEDC. Empirical relationships
are developed from these data and a judgment made whether to use existing
empirical relationships or the relationships developed in this study. An
existing relationship (Lipner et al.) is used to predict velocity; the
empirical relationships developed in the course of this study are used to
predict acceleration and displacement. The ground motions are presented in
table form and as contour plots. Included also is a discussion of damage
criteria from blast and earthquake studies. This report recommends using
velocity rather than acceleration as an indicator of structural blast
damage. It is recommended that v = 2 ips (v = .167 fps) be used as the
damage threshold value (no major damage for v < or = 2 ips).

A comprehensive program for prediction of hydraulic fracture azimuth is
being conducted in the tight, lenticular, gas sandstone reservoirs of the
Mesaverde Group in the Department of Energy's Multi-Well Experiment near
Rifle, Colorado. Methods used in the program can be divided into two
groups: (1) indirect, predictive techniques which determine either the
principal paleo-stresses or in situ stresses prior to fracturing and (2)
direct observation from either geophysical detection of hydraulic fracture
propagation or wellbore impression-packers of open-hole hydraulic
fractures. Predictive methods which determine the paleo-stress directions
include geologic observations of the orientation of normal faults and
fractures at the surface and in oriented core, and twinned calcite strain
analysis of oriented core. These methods show a consistent direction of N75
exp 0 W plus or minus 10 exp 0 for the maximum horizontal paleo-stress.
Predictive methods which determine the in situ stress directions include
(1) oriented core analysis using anelastic strain recovery measurements and
differential strain curve analysis, (2) oriented caliper and televiewer
logs to infer stress directions from wellbore breakouts, and (3) computer
modeling of the horizontal stress directions due to gravitational loading
of topographic relief. The results of these methods are fairly consistent,
and are in general agreement with the paleo-stress results, but also
suggest a possible 20 exp 0 clockwise rotation with depth of the maximum
horizontal in situ stress from N89 exp 0 W plus or minus 10 exp 0 at a
depth of 1330 m to N68 exp 0 W plus or minus 9 exp 0 at a depth of 2450 m.
The clockwise rotation of the horizontal stresses with depth may be due to
large, local topographic relief superimposed on the regional stress field
of the basin. 39 references, 6 figures, 5 tables. (ERA citation 09:039632)

The launch induced vibro-acoustic environments have been forecast for
several Ground Support System structures at V23, the STS launch facility at
Vandenberg, AFB. These forecasts are based on site particular vibration and
pressure responses determined by an explosive sounding program conducted at
V23. The responses are coupled with an STS acoustic pressure term
established by measurement of STS launches at KSC. This report provides a
summary of the results of this effort and provides the forecasts for the
vibration environment in the PPR. Motion levels in the PPR are found to be
substantially below all levels of concern. However, companion studies have
shown that high accelerations can be anticipated in the OFS Room and the
PCR. In addition, pounding could occur between PCR and PPR. Strong
reverberations on acoustic records from V23 indicate that launch
overpressures at V23 will be significantly altered from those at KSC for
the shuttle at altitude and clear of the ground. Finally, the potential of
pounding due to earthquake ground motions is discussed.

Modal parameters determined from response measured in dynamic tests and
from analytical models for simulating the tests and two subsequent
earthquakes experienced by the containment building of Unit 1 of the
Fukushima Power Station complex in Japan are compared for the purpose of
evaluating the effectiveness of the dynamic tests in earthquake response
prediction. The tests are found to have led to the correct identification
of a fundamental frequency. The lack of agreement between test- and
earthquake-determined modeshapes and damping is attributable more to the
shortcomings of the simulation models than to differences in actual
behavior.

There is a need to measure and analyze the vibro-acoustic environment of
Space Transportation System (STS) launches in order to forecast and verify
00 @Z'

facility design and lifetime predictions for STS operations at Vandenberg
Air Force Base (VAFB), and to accumulate flight vehicle performance data.
Earlier measurements at Kennedy Space Center (KSC) pointed to an azimuthal
dependence in the overall sound power level (OASPL) for STS launches. The
immediate aim of this effort is to clarify the azimuthal properties of
surface pressure around the time of the OASPL maximum for KSC launches. The
study helps define and locate a site insensitive STS source pressure
equivalent essential to vibro-acoustic forecasts at VAFB. The dense
watercloud produced by STS main engine firing at KSC attenuates surface
pressure levels directly south of Pad 39A by as much as 14db. Spectra at
stations under the cloud are lower in level and frequency content than
those in the clear. The phase velocity for acoustics early in the launch is
insensitive to watercloud effects for stations at 300 meters. Spatial
coherence of the pressure field is degraded between stations 100 meters or
more apart.

The mine Nowa Ruda is the most dangerous mine in Poland with regard to
gas and rock bursts. This special danger is due to the very complicated
geological structure of the strata and the thick network of tectonic
disturbances (folds, cracks). This tendency of the seams to outbursts is
related not only to their high gas content (CH sub 4 : up to 7 m exp 3-/t;
CO sub 2 : up to 35 m exp 3 /t) but also to the loose structure of the coal
(approximately 30 to 80 kg/cm exp 2 ). Up to March, 1979, 1299 coal and gas
outbursts were observed in Nowa Ruda. In order to control the outburst
hazard in the mine, the following measures are applied: continuous
prediction of the hazard based on measurement of the pressure; desorption
and the gas emission in test boreholes; active methods for control of the
hazard; limitation of the range of consequences of induced outbursts;
system of warning to underground workers; and seismic and seismo-acoustic
methods for prediction of outbursts. The multiplicity of the protective
measures forms the main basis of safe working in districts subject to

outbursts. Both the methods of prediction and also the measures applied to
reduce the hazard may be unreliable. While these are being perfected one
should also make strenous efforts to develop a system for safeguarding
workers from unpredicted outbursts.

The seismic stability of embankment dams may be evaluated by a relatively
simple methodi originally proposed by N. M. Newmark, in cases where there
is no threat of liquefaction or severe loss of shear strength under seismic

shaking. This method is based on idealization of the potential slide mass
as a sliding block on an inclined plane which undergoes a history of
earthquake-induced accelerations. The result is a computation of the
expected final displacement of the block relative to the base. A necessary
refinement is the consideration of amplification of the base motions in the
embankment, which is evaluated by means of a linear elastic analysis.
Sliding block analyses have been done for 348 horizontal components of
natural earthquakes and 6 synthetic records. These computations, together
with available results of amplification analyses, suggest that a
pseudostatic seismic coefficient analysis would be appropriate for
embankment dams where it is not necessary to consider (a) liquefaction or
severe loss of shear strength, (b) vulnerability of the dam to small
displacements, or (c) very severe earthquakes, of magnitude 8 or greater. A
factor of safety greater than 1.0, with a seismic coefficient equal to
one-half the predicted bedrock acceleration, would assure that deformations.
would not be dangerously large. (Author)

This monograph reviews possible responses on the part of groups,
organizations, and political bodies to scientifically credible earthquake
predictions. Following a discussion of the status of earthquake prediction,
the book describes the methods used to gather the data on which its
determinations are based. A model of earthquake prediction and warning is
presented, divided into three elements--giving information, interpreting
information, and responding to information. The responses of people and
groups are estimated with reference to the three elements. The final
chapter suggests options for public policy and action to maximize benefits
and minimize costs of earthquake prediction.

The strong ground motion that will result from damaging earthquakes that
occur in South Carolina, varying in size from those that can produce only
minor damage to those as large as the 1886 event, was estimated. The report
is divided into three parts. Part I discusses acceleration, velocity and
displacement modeling, using available observational data (accelerograms
and'non-strong motion seismographic) and response spectra obtained from
those data. Part II uses MM intensity data for estimating strong ground
motion. Part III presents surface-wave focal mechanism studies of South
Carolina earthquakes. (ERA citation 09:021152)

An analysis of the available world earthquake-occurrence data was
completed and the existence of an upper bound on earthquake magnitude was
demonstrated. The analysis demonstrated that the shape of the
frequency-magnitude curve is statistically the same everywhere in the world
for both seismically active and inactive regions. This universal shape was
found to be valid for regions as small as tectonic zones, and good results
(within the limits of data accuracy) were obtained for single-site
excavations. The results can be used to derive best-estimate values for
earthquake risk. .

The correct application of the square root of the sum of the squares
(SRSS) rule is presented for obtaining the combined responses of a
subsystem to seismic excitations given by orthogonal earthquake components
represented by system response spectra. Alternate methods of applying the
SRSS, which are sometimes used either for simplicity or due to different
interpretation, are evaluated and compared with the correct method. The
evaluations consider the following four cases: (1) the correct method which
combines the responses in a particular direction given by each earthquake
component as a last step, (2) a generally unconservative method whereby
both the system response spectra and the resulting subsystem responses are
combined by the SRSS, (3) a method which can be unconservative for unequal
earthquake components where the system response spectra are combined by the
absolute sum and the resulting responses by the SRSS, and (4) a
conservative method which combines the system response spectra by the SRSS
but adds the resulting responses absolutely. In addition, three conditions
of directional coupling are considered for all cases. These are full
directional coupling, only the system coupled, and no coupling. A
comparison of the subsystem combined responses with the various SRSS
methods is presented in tabular form which gives the applicable equations
for each case and coupling condition. (ERA citation 09:006731)

Historically, earthquake-induced liquefaction has caused an enormous
amount of damage in terms of loss of human life, property damage, human
suffering and environmental damage. A probabilistic three-dimensional
liquefaction model is proposed here considering the damage aspect of the
problem. Considerable uncertainty is expected in the estimation of several
parameters in a liquefaction model. The estimation of in situ relative
density is one of them. A new relationship, designated as the Haldar and
Miller relationship, is proposed here between the Standard Penetration Test
value and the in situ relative density. The in-situ shear resistance of a
soil deposit is evaluated here by introducing a shear strength parameter R.
Using large-scale shaking table test results, the relationship is corrected
for the compliance effect, sample preparation methods, mean grain size,
multidirectional shaking and some other secondary factors. There is also
high uncertainty in the load parameters. Hence, the seismic activity of the
region should bve given serious attention in a liquefaction study. This
probabilistic model is a first step toward developing a comprehensive
decision analysis framework. Recommendations are also made here for future
research work in the area of liquefaction.

This report examines the use of probabilistic methods in dealing with the
problem of potential earthquake-induced liquefaction of foundation soils at
an example dam site located in the central United States, near the New
Madrid earthquake -zone. The example dam is assumed to be a 1-mile long
rolled-filled embankment founded on a 100-ft deep deposit of interbedded
alluvial gravels, sands, silts, and clays. The study is seen as an
opportunity to examine probabilistic concepts and procedures in the
framework of an example engineering project. In this context, the main
practical value of a probabilistic approach is that it permits more
informed decision making about further data acquisition, additional
engineering analysis, and if necessary, remedial action. The specific aim
of the study is to show how probabilistic procedures complement and help to
reinterpret the results of deterministic (earthquake-induced) liquefaction
analysis. The procedures focus on evaluating the impact of the different
sources of variability (in the input parameters) on the uncertainty in
performance predictions, and they permit results of the liquefaction
analyses to be seen in the broader framework of assessment of
earthquake-related dam failure risks.

with conclusions and recommendations for advanced interior intrusion
detection concepts to be tested in brassboard. The report discusses
potential sources and properties of intrusion signals, measurement
techniques, and signal processing methods to extract range and correlating
data. It has been found that many techniques have the potential for ranging
and correlation of intrusion signals, however few of these are accomplished
in a straightforward, practical sense. Through the derivation and
application of evaluation criteria, several-candidates were selected for
further study in breadboard experiments. The breadboard tests afforded a
first hand opportunity to measure and compare the anticipated performance
of these candidates. The outcome of the experiments then formed the basis
for recommending concepts to be explored further in brassboard development.

Munition actuation signals are generated by an acoustic target ranging
system that predicts the time and distance of closest approach of a moving
target to a munition. The predictive capability of the system is based on
the rate of change of the sound level emanating from the target compared to
its absolute magnitude. The system generates munition standby, arm and fire
signals by differencing the received acoustic amplitude function signal and
its first derivative and subsequently comparing the difference signal with
various reference level signals. The reference level signals are a function
of munition effective range and target conditions. Mechanization of the
system is realized by simple circuitry consisting of an acoustic signal
detector and processorl a differentiating operational amplifier, a
progammable gain amplifier, a reference level signal source, an adder and a
comparator circuit. (Author)

This report describes available evidence for effects of moving sources in
earthquakes and analyzes them in terms of the physics of wave emission. The
study is addressed mainly to questions arising in geotechnical
investigations for engineering purposes and suggestions are made on the
significance of the effect in strong ground motion estimation. From a
seismological point of view, the effect of the moving source has been
clearly demonstrated in numerous studies using seismographs located at both
moderate and great distances (i.e., the far field) from the source. Such
studies, however, usually concern long-period seismic waves with periods
above 2 to 5 seconds. Second, when seismic waves in the near field with a
range of wave frequencies characteristic of engineered structures (i.e., 1
Hz to 10 Hz) are considered, there is as yet only limited definitive
evidence available, and this is somewhat contradictory. Nevertheless, the
likelihood is that the elementary predictions of the magnitude of the
effects can be sometimes modified by other features of the source
mechanism, the geological variations along the wave paths and within the
fault zone. Third, the ratio of peak horizontal ground motion in the
forward direction of fault rupture to the peak motion in the backwards
direction is probably greatest for ground displacements and velocities and
least for peak accelerations. High frequency ground accelerations show
variations due to scattering, attenuation, and source asperities that mask
directivity effects.
