The National Oceanic and Atmospheric Administration (NOAA) of
the Department of Commerce has assigned responsibility . for
operating the Tsunami Warning System to the National Weather
Service. The National Weather Service succeeds the Environmental
Research Laboratories and the National Ocean Survey of NOAA and,
previously, the U.S. Coast and Geodetic Survey in this capacity.

The T sunami Warning System is a cooperative effort among
nations bordering the Pacific Ocean to provide early warning of
potentially disastrous seismic sea waves (tsunamis). Seismograph
and tide data are collected' and communicated to the Tsunami
Warning Center in Honolulu, Hawaii, for analysis. and evaluation.
If warranted, tsiinami watches and warnings are disseminated
immediately by the Center t6 affected coastal populations. Since
the Tsunami Warning System operates under emergency conditions,
all participants nust carry out their functions promptly. The
objective of this plan is to facilitate efficient operation of the
system; therefore, all participants should become thoroughly
familiar with the contents of the plan and rigorously follow
prescribed procedures.

SECTION 1. TSUNMIS

1.1 @7ATURF A14D ORICIN

A tsunami or seisnic sea wave is a series of waves of extremely long wavelength and
period caused by an underwater disturbance. Although most tsunamis are associated with
large earthquakes in whic'i the epicenters underlie or border the ocean floor, the generating
ncchanisr is not positively 1,rown@ Vertical displacement of the ocean floor during an
eartlhqual-ze may be responsible, or possible submarine avalanches on the slope of oceanic
trenches, or generation of resonant oscillations of trench water by long-period earthquake
waves. Subnarine volcanic eruptions also have been '@nown to generate tsunamis.

All submar'ne earthqual@es do not produce ts=m@is, and all tsunamis are not large
enough to cause damage; however, occasional large waves have caused great destruction and.
loss of life in coastal areas. At present, there is no way to deter-mine if an earthquake
has generated a tsunami, except to note the occurrence and epicenter of the earthquake and
then detect the arrival of the characteristic waves at a network of tide stations. The
waves, although often called tidal waves, have nothing to do with the tides.

1.2 FREQUENCY OF 0 CCURRENCE

During the 74-year period from 1900 to 1973, 200 tsunamis were observed or recorded in
the Pacific Occan. Forty-one caused casualties and damage near the source only; nine caused
widespread destruction throughout the Pacific. Almost one-third of the total tsunamis were
generated in or near Japan, although most of these were minor.

The g .reatest number of tsunamis during -any.1 year i4as 11 in 1938. All were minor and
caused no damage. Only 9 years of the period'were free of tsunamis.

The distribu tion of tsunami generation in other areas is as follows: South Pacific, 14
percent; South America, ln percent; Formosa, Philippines, Ryukyn Islands region, 11 percent;
Kuril Islands and Kamchatka, 10 percent; Mexico and Central America, 7 percent; Alaska and
Aleutian Islands,' 6 percent; Indonesia, 5 percent; West Coasts of Canada and the United
States, 2 percent; and Hawaii, 2 percent.,

1.3 PROPAGATION

Tsunamis travel outward in all directions from the 'generating area. Their speed
depends on the depth of water, so that the waves undergo accelerations and decelerations in
passing over an ocean bottom of varying depth. In the deep and open ocean, they travel at
speeds of 500 to 1000 kilometers per hour (300 to 600 miles per hour). The distance between
successive crests can be as much as.500 to 650 kilometers (300 to 400 miles); however,'in
the open ocean, the height of tile waves may be no nore than 3n to 60 centimeters (1 or 2
feet), and the waves pass unnoticed. Variations in tsunami- propagation result when the
propagation impulse is stronger in one direction than in others because of the orientation
or dimensions of the generating area and where regionalitopog-raphic features modify both the
wave form and rate of advance. Upon reaching shosler water, the speed of the advancing wave
diminishes, its len.-th decreases, and its height increases greatly, owing to the piling up
of water. Configuration of coastline, shape of ocean floor, and character of advancing
waves play an inportant role in the destruction wrought by tsunamis along any coast, whether
near the generating area or thousands of kilometers from it. Consequently, detection of
relatively snall tsunamis at any locality warrants immediate reporting- -through the Tsunami
Warning @ystem-to spread the alarm to all coastal localities of approaching potentially
dangerous waves.

1.4 OBSERVABLE FEATURES

The successive waves of a tstinami in the deep sea have such .,reat length anc! so little
hei.-lit they are not visually recognizable from a surface vessel or fron an airplane. The
passing waves produce only a gentle rise and fall of the sea surface. During the April 1946
tsunami at Hawaii, ships standing off the coasts observed tremendous waves breakinf on shore
but did not detect any change in sea level at their offshore locations. At present,
detection of tsunamis is possible only near shore where the shoaling effect described in
topic 1.3 can be observed. The first visible indication of an approaching tsunami is often
a recession of water caused by the trough preceding an advancing wave. Any withdrawal of
the sea, therefore, should be considered a warning of an approaching wave. A rise in water
level also may be the first event. Tide-gage.'records of the Chilean tsunami of May 22,
1960, generally showed a rise in water level as the first inaication of this tsunami. This
rise amounted to about one-half the amplitude of the following decrease in water level.
Under certain conditions, the crest of an advancing wave can overtake the preceding trough
while some distance offshore. This causes the wave to proceed shoreward as a bore-7a wave
with a steep churning front,

1.5 DESTRUCTIVE FORCE

The force and destructive effects of tsunamis should not be overlooked. At some
places, the advancing turbulent wave front is the most destructive part of the wave. Where
the rise is quiet, the outflow of water to the sea between crests may be rapid and
destructive, sweeping all before it and undermining roads, buildings, and other works of man
with its swift currents. Ships, unless moved away from shore, can be thrown against
breakwaters, wharfs, and other craft or washed ashore and left grounded during withdrawals
of the sea.

In the shallow waters of bays and harbors, a tsunami frequently will initiate seiching.
If tsunami period is related closely to that of the bay, the seiche is amplified by the
succeeding waves. Under these circumstances, maxinizi wave activity often is observed much
later than the arrival of the first wave.

1.6 PERIOD AND DURATION

A tsunami is not one wave, but a series of waves. The time that elapses between
passage of successive wave crests at a given point usually is from 10 to 45 minutes.
Oscillations of destructive proportions may continue for several hours, and several days may
pass before the sea returns to its normal state.

1.7 HISTORICAL TSUNNIIS

The most destructive tsunami of recent history was generated along the coast of Chile
on Hay_ 22, 1960. No accurate assessment of the damage and deaths attributable to this
tsunami along the coast of Chile can be given; however, all coastal towns between the 36th
and the 44th parallels either were destroyed or heavily damaged by the action of the waves
and the quake. The combined tsunami and earthquake toll included 2,000 killed, 3,000
injured, 2,000,000 homeless, and $550 million danage. Off Corral, the waves were estimated
to be 20.4 meters (67 feet) high. The tsunami caused 61 deaths in Hawaii, 20 in the
Philippines, 3 in Okinawa, and 100 or more in Japan. Estimated damages weTe $50 million in
Japan, $24 million in Hawaii ' and $1 million along the west coast of the United States.
Wave heights varied from slight oscillations in some areas to ranges of 12.2 meters (40
feet) at Pitcairn Island; 10.7 meters (35 feet) at Hilo, Hawaii; and 6.1 meters (20 feet) at
various places in Japan.

Major tsunamis normally are associated with great earthquakes of magnitude 8 or larger;
however, on April 1, 1946, an earthquake of magnitude 7.2 south of Unimak Island in the
Aleutian Islands generated a tsunami that left 159 dead in Hawaii. Waves of 9 to 17 meters
(30 to SS feet) were observed throughout the islands, demolishing many structures. Near the
tsunami source, a lighthouse at Scotch Cap on Unimak Island was destroyed by waves that
surged to a h6ight of over 30 meters (100 feet).

(74

Two of the most devastating tsunamis were caused by the great Krakatoa explosion of
August 27, 1883, and the Sanriku earthquake of June 15, 1896. The former caused waves of
over 30 meters (100 feet) that drowned 36,500 persons in western Java and southern Sumatra.
The latter caused waves up to 30 meters (100 feet) at the head of Kamaishi Day and the loss
of 27,000 lives.

The costliest tsunani ever to strike the United States was generated by the Prince
William Sound, Alaska, earthquake of March 28, 1964. Fatalities totaled 122, and over $94
million in damage resulted in Alaska, California, hawaii, Oregon, and Washington.

@FcTTON II. THE TSUNAMI WARNING SYSTEM

2.1 HISTORY

After the Aleutian tsunami of April 1, 1946, caused major damage and many casualties in
the Hawaiian.Islands, the Coast and Geodetic Survey (C&CS) began to develop a means of
providing warning to the population of Hawaii in the event of the occurrence of another
tsunami. To accomplish this, C&GS had to solve a number of technical problems.

To.be effective, a warning system had to be able to detect and locate rapidly.
earthquakes in the Pacific region and, if an earthquake occurred in an area where tsunami
generation was possible, to determine quicklywhether a tsunami had in fact been generated.
In addition, a method had to be developed whereby accurate arrival times of the tsunami at
various places could be forecast.

For meeting this last requirement, a tsunami travel time chart for Honolulu was
prepared (figure 4). The chart consists of a series of more or less concentric lines
overprinted on a chart of the Pacific Ocean. The lines represent distances from Honolulu
for each half hour of the wave travel time. To Honolulu, travel time is obtained by
plotting the epicenter of an earthquake on the chart and noting its position with respect to
the time lines. When given the time of the disturbance, the arrival time of the first wave
of the tsunami, at the Honolulu tide station becomes immediately available. Travel time
charts also are prepared for the other tide stations in the Tsunami Warning System (TWS).
Because,some tide stations in tl@e TWS had relatively poor communications and because
tide gages normally are checked only once a day, C&GS personnel designed a tsunami detector
that is actuated by the wave motion of a tsunami to ring an alarm. The alarm, located where
it would always be heard by personnel at a tide station, insures an early warning that a
tsunami has been generated whether a request for data has or has not been received at the
tide station. Since the-detector normally is actuated by the first part of the waive motion,
before the arrival of the destructive part, it can be used locally to sound an alarm.

In 1946, photographic techniques generally were used for recording earthquakes because
they were simple, practical, and precise. The TWS, however, needed visible recording
equipment that could be used in conjunction with existing seismographs. Various
instrumental systems were tried before one was selected. In 1947 and 1948, the new
instruments were built and installed at three C&GS observatories. These installations were
modified during @the summer of 1950 by the addition of a new amplifier.developed by C&GS
scientists. The new amplifier included an alarm circuit so that, whenever a major
earthquake was recorded, an audible and/or visible alarm was tripped, thus insuring the
prompt observation of all major earthquakes.

Since the 'system would not operate often enough to justify the maintenance of an
extensive communication network, the collaboration of the armed forces and the Civil
Aeronautics Administration (now the Federal Aviation Administration) was sought. At a
meeting on August 12, 1948, attended by representatives of the U.S. Army, Navy, Air Force,
the CAA, and the Coast and Geodetic Survey, a tentative communication plan was approved and
the operation of the Coast and Geodetic Survey's Seismic Sea Wave Warning System, now the
Tsunami Warning System, began.

Initially, the TWS consisted of the C&GS seismological observatories at College and
Sitka, Alaska; Tucson, Arizona; and Honolulu, Hawaii; and tide stations
at Attu, Adak, Dutch Harbor. and Sitka, -Alaska; Palmyra Island; Midway Island;
Johnston Atoll; and Hilo and Honolulu, Hawaii. Additional seismological and tide stations
have joined or left the TWS. The currect participants are listed in section VII.

Initially, the TWS was to supply tsunami watch and warning in-_%rmation to the civil
authorities of the Hawaiian Islands and to various nilitary headquarters in the Hawaiian
Islands for dissemination to military bases throughout'the Pacific and to islands in the
U.S. Trust Territory of the Pacific. Beginning in October 19S3, the first addition to the
areas receiving warnings was made--the warning information furnished to the civilian
authorities. in the Hawaiian Islands. also was given to the Civil Defense agencies of
California, Oregon, and Washington. The great destruction caused by the May 1960 Chilean
tsunami prompted a large number of countries and territories to join the TVIS. Current
recipients of tsunami watch and warning information are listed in topic 8.2.

2.2 OBJECTIVES

The objectives of the Tsunami Warning System have been stated in various ways in
different publications. Essentially, the system has the function of detecting and.locating
major earthquakes in the Pacific region, determining whether they have generated tsunamis,
and providing timely and effective tsunami information and warnings to the population of the
Pacific to minimize the hazards of tsunamis, especially those to human life and health.

2.3 DESCRIPTION

The TIVS requires the participation of many seismic, tide, communication, and
dissemination facilities operated by most of the nations bordering the Pacific. Operational
control of the system 'is maintained by the Director of the Tsunami Warning Center at
Honolulu Observatory, Hawaii.

Functioning of the system begins with the detection, by any participating seismic
observatory, of an earthquake of sufficient size to trigger the alarm attached to the
seismograph at that station. The alarm thresholds are set for each station so that ground
vibrations of the amplitude and duration associated 'with an earthquake of approximate
magnitude 6.5 or greater anywhere in the Pacific region will, cause' thel.1 to sound. This
magnitude is below the threshold for issuing watch and warning messages.. Personnel at the
station immediately interpret their seismograms and send their readings to Tionolulu
Observatory (110). Upon receipt of a- report from one of the participating seismic
observatories or as a consequence of the triggering of their own seismic alarm, HO personnel
send messages requesting data to the observatories in the system.

When sufficient data have been received for 110 to locate the,earthquake and compute the
magnitude, a decision is made as to further action. If the earthquake is strong enough to
cause a tsunami and is located in an area where tsunami generation is possible, HO will
request participating tide stations located near the epicenter to monitor their gages for
evidence of- a tsunami. Watch bulletins are issued to the dissemination agencies for
earthquakes of magnitude 7.5 or greater (7 or greater in the Aleutian Island region),
alerting then to a possibility that a tsunami has been generated and providing data that can
be relayed to the public so necessary prelininary precautions can be taken. A watch also
may be disseminated by HO upon the issuance of warnings by regional warning centers. Since
the regional systems use different criteria for their disseminations (appendix A for
Alaska), a watch may at times be issued by HO for earthquakes with magnitudes less than 7.5.

When reports are received from tide stations, they are evaluated; if they show that a
tsunami has been generated that. poses a threat to the population in part or all of the
Pacific, a warning is transmitted to the dissenination agencies for, relay to the public.
The dissemination agencies then implement predetermined plans to evacuate people from
endangered areas. If the tide station reports indicate that either a negligible tsunami or
no tsunami has been generated, HO issues a cancellation of its. previously disseminated
watch.

2.4 REGIONAL WARNING SYSTEMS

A tsunami originates in or near the epicentral area of the earthquake that creates it.
A tsunami travels outwhrd in all directions from this epicenter at a speed that depends on
ocean depths. In the deep ocean, the speed may exceed 925 kilometers per hour (500 knots);
thus, the need for rapid data handling and communication becomes obvious. Because of the
tine spent in collecting seismic and tidal data, the warnings issued by the Honolulu

Observatory cannot protect areas against tsunamis generated in adjacent waters. For
providing sor: measure of protection against local tsunamis in the first hour after
.e
generation, regional warning systems have been established in some areas.

To function effectively, these regional systems generally have data from a number of
seismic and ti(e stations telenetered to a centr,,.l headquarters. Nearby earthquakes are
located, usually in 15 minutes or less, and a warning based on seisnological evidence is
released to the population of the area. Since the warning is issued on the basis of seismic
data alone, one ray anticipate that warnings occasionally will be issued when tsunamis have
not been generated. Since the warnings are issued only to a restricted area and
confirmation of the existence or nonexistence of a tsunami is obtained rapidly, dislocations
due to the higher level of protection are ninimized. Among the most sophisticated of the
.regional systems are those of Japan and Alaska. The Alaskan system is described in appendix
A. The description of the Japanese system may be found in the publication by the Japan
Meteorological Agency (1963) or in the paper by Wadati et al. (1963).

3.2 FACILITIES TO BE USED
To ensure the timely and effective operation of the TWS, communication facilities
capable of handling rapidly the data requests from HO, seismograpl@ and tide reports to Flo,
and watch and warning messages are essential. Since such traffic is relatively infrequent,
existing communication channels are used with some supplementation where absolutely
necessary, instead of establishing a separate communication system that would, to a large
extent, duplicate existing channels. Hence, the communication channels under the management
and'control of the DCA, FAA, NASA, the Army, Navy, Air Forcej Coast Guard, various foreign

agencies, and private companies, as outlined herein, will be used to handle the message
traffic involved between HO and. the several seismological and tide stations and
dissemination agencies participating in.the warning system.

3.3 PRECEDENCE AND PRIORITY OF MESSAGES

3.3.1 "Live" or actual distress traffic

Data requests, seismograph reports, tide reports, and other messages containing factual
reports of unusual natural phenomena that may cause or have caused a condition of distress
normally will be assigned Flash precedence when intended for transmission via DOD
communication channels. Messages of these types when prepared for transmission via APTN or
FAA communication facilities will be assigned SS priority, which will afford handling on
civil circuits substantially equivalent to the handling of Flash precedence traffic on DOD
circuits; when prepared for transmission via NASA communication facilities, they will be
assigned Urgent precedence. The originator of any message of the above types may assign a
lower precedence or priority if the desired speed of handling or other circumstances so
warrant.

3.3.2 "Dummy" or test message traffic

Test traffic (including dummy messages to determine transmission time under. various
conditions or for other purposes) and similar types of messages will be assigned appropriate
precedence or priority by the originator. Message traffic of these types, when intended to
determine probable transmission time under actual distress conditions or over various
routes, normally will be assigned Immediate precedence for transmission over DOD channels,
Urgent for NASA channels, or SS priority for transmission via FAA channels,but must include
the words "TSUNAMI DLPIMY11 for proper identification. Such messages may be assigned a lower
precedence or priority at the discretion of the originator.

3.3.3 Routine data message traffic

Reports of instrument failure or deficiency and -similar routine message traffic
nDrmally will be assigned Routine precedence for transmission via DOD or 14ASA channels or FF
priority for handling via FAA circuits.

3.3.4 Transfer between Military, FAA and NASA channels

If any message bearing Flash or Immediate precedence is passed from a DOD channel to an
FAA communication statitin for relay, the FAA operating personnel will handle it as a.message
of SS priority. If any message bearing Flash or Immediate precedence is passed from a
military channel to a NASA communication station for relay, the NASA operating personnel
will handle it as a message of Urgent precedence. A message bearing any precedence lower
than Immediate that is passed from a DOD channel to FAA or NASA for relay will be handled as
a message of correspondingly lower priority or precedence. The same principles apply to
messages passed from FAA or NASA channels to DOD communication facilities for relay. A
recommendation is that, insofar as practicable, FAA and NASA personnel change (or convert)
the format and the priority or precedence indicator on a message to the equivalent DOD
format and precedence designation before passing the message to a DOD communication activity
for relay. (See to pic 3.4.1.)

3.4 PREPARATION OF MESSAGES BY ORIGINATOR

For permitting correct identification of messages, providing for proper handling, and
facilitating evaluation, each message will contain certain elements that are listed in the
sequence in which they will appear in each message, together with an explanation, in topics
3.4.1 through 3.4.5.

3.4.1 Precedence designation (or priority indicator)

A precedence designation (or priority indicator for civil aviation facilities) is used
to indicate 'the relative order in which a message of one precedence designation (or

priority) is handled or processed with respect to all other messages. Precedence
designations and priority indicators express or signify:

To the originator-the required (or desired) speed of delivery to the addressee;

To communication personnel-the relative order of handling and delivery; and

To the addressee--the relative order in which he should note the message.

Messages pertaining to the TWS normally will not be assigned a precedence higher than
Flash or Urgent nor a priority higher than SS. (See the following tabulation.) Hence, the
originator will assign to each message an appropriate DOD precedence desiFnation [identified
by (M)], a civil aviation prkority indicator [identified by (C)], or a NASA precedence
designation (identified by (N)].

Precedence Designation Explanation

(1) Flash (m) Z Flash messages are processed, transmitted,
(C) SS and delivered in the order received and
(N) W ahead of all messages of lower precedence.

(2) Immediate Q0 0 Immediate messages are processed, trans-
CC) SS mitted, and delivered in the order
(N) UU received and ahead of ali messages of
lower precedence. See NOTE.

(3) Routine (M) R Routine.messages are processed, transmitted,
(C) FF and delivered in the order received and
(N) RR after all other messages of. higher
precedence.

NOTE: 71,.e FAA priority indicator SS and the NASA precedence Urgent usually will afford
more rapid handling than Immediate precedence on DOD circuits; however, the lack of exact
equivalents between DOD and NASA precedences and civil priorities is not a matter of
significant consequence. (See topic 3.3.)

3.4.2 Date-time group

A date-time group will be assigned to each message by the originator to indicate the
day, hour, and minute (expressed in Greenwich Meridian Time) at which the preparation of the
message actually is completed by the originator. The date-tine group consists of:

Two digits (from 01 to 31) to denote the day of the month.

Four digits to denote the hour and minute of the day expressed in the 24-hour system,
the first two (from 00 to 23) to indicate the hour and the last two (from 00 to 59) to
indicate the minute.

The zone suffix letter Z to denote that the day, hour, and minute are expressed in
Greenwich Meridian Time. For example, the date-time group of a message completed by
the originator at 0821 GtIr on April 3 would be 030821Z. The date-time group serves as
identification for any specific message and also aids the addressee in evaluating a
message since it establishes the exact time of the origin. Hence, all originating
personnel are cautioned to insure that the dAte-time group is accurate.

3.4.3 Originator

The originator will be identified by th e designator assigned to the station at which
the message is prepared. The designators for all stations are listed under the caption

and guidance of all personnel involved, but are not intended to limit individual ' initiative.
The methods are listed in order of relative preference on the basis of presently available
information, but changes in relative preference by any station as warranted by local
conditions and previous exPerience are authorized. Furthermore, all personnel involved,are
urged to exercise individual ingenuity and initiative as dictated by local circumstances at
the time of emergency to accomplish transmission of each message to the addressee reliably
and rapidly. For the transmission of messages via telephone, which will be necessary in
some instances, observance of the following precaution is essential to prevent mistakes in

wording or transposition of figures in the seisnograph reports. After copying the entire
message, the person receiving the message will verify each word and group by repeating it to
the person sending the message and securing acknowledgment.

NOTE: Any toll charges incident to the use of copmercial facilities for the
transmission of messages between an Army, Navy, Air Force, or FAA communication activity and
any other station participating in the TWS will be borne by the National Ifeather-Service.

transmitting messages between seismic and tide stations and dissemination agencies and U.S.
military, FAA, or NASA communication facilities.

SECTION IV. SEISMOGRAPH STATIONS

4.'l FUNCTION

Seismological stations (as listed in topic 7.2) detect earthquakes and submit
seismograph reports that-are the basis for the determination of earthquake epicenters and
magnitudes by Honolulu Observatory (figure 1) and regional warning centers. Seismograph
stations are requested to participate in the warning system whenever needed for the prompt
location of epicenters and the determination of earthquake magnitudes.

4.2 DUTIES AND RESPONSIBILITIES

Seismograph stations report to 110 and, if so instructed, to regional warning centers
P-phase arrival times for all large earthquakes in the Pacific as soon as possible after
they are recorded. Individual observatories may be alerted that an earthquake has occurred
either by an alarm attached to one of their instruments or by arrival of a request for data.
In addition, the seismogranh stations should submit S-phase, magnitude, and depth-phase data
(reported as AP) either in the initial message, if these data can be included without
causing delay, or in a second message.

4.3 CO"MICATIONS

Before a seismograph station can be incorporated into the warning system, adequate
communication facilities must be available on a 24-hour-a-day basis. This requirement is
due to the fact that tsunamis can strike at any time of day or night and reliable fast
communication facilities must be-immediately available.

In the case of stations located outside the United States oT its possessions, the
agency involved must assume the cost of any commercial communications involved in the
transmission of messages to and from a U.S. or AFrN communicatio n facil ity.

For speeding the collection of data, studies are being made of ways to telemeter the
data directly to Honolulu in real time, either continuously or on an as-needed basis.
Various types of transmission are being considered, including satellite relay, cable, and
radio.

For testing the operation of the warning system, for keeping communication-operating
personnel familiar with the procedures for handling message traffic pertaining to the
system, and for determining transmission times, dummy or test messages are sent monthly to
all stations.-

For the NWS to evaluate the operation of the warning system, all participants must
submit logs covering periods of tsunani emergencies. These logs must include the text and
time of transmission of all messages sent and the text and time of receipt for all incoming
messages. If the station was alerted by an alarm attached to a seismograDh, the time of
such alerting should be noted. If tsunani effects are reported from the vicinity of the
station, a summary of these effects should be included. .,The logs should be mailed to the
Associate Director, MeteoroloFy and Oceanography, National Weather Service, National Oceanic
and Atmospheric Administration, Silver Spring, Maryland 20910, as soon as possible after
each occurrence.

SECTION V. TIDE STATIONS

5.1 FUNCTION

Tide stations (as listed in topic 7.3) detect tsunamis by means of recording tide gages
or automatic sea-wave detectors and submit reports to 110 when requested or on their own
initiative whenever a tsunami is detected. In areas where no tide stations participate in
the warning system, additional stations will be sought whenever required to provide early
confirmation that a tsunami has been generated, thus giving an earlier warning to those
areas receiving tsunami warnings. As research progresses into methods of predicting wave
runup, most likely additional tide stations will be needed to provide raw data on which to
base predictions. As the system is expanded to provide warnings to new areas, additional
tide stations frequentl@ are required.

5.2 DUTIES AND RESPONSIBILITIES

Tide stations report to HO and to regional warning centers as instructed whenever a
tsunami is detected-or whenever they are queried. The onset of a tsunami should be reported
as soon as possible and should include information on the initial rise or fall. Subsequent
messages should be filed at intervals of approximately 0.5 hour for at least 2 hours and
should give details of the wave action and a summary of local effects. If wave action still
is increasing or damaging waves still are occurring at the end of 2 hours, the tide observer
-should continue reporting at 0.5-hour intervals until wave action decreases and damaging
waves cease. Wave amplitudes should be measured from crest to trough or trough to crest.
If the tide gage is destroyed or inaccessible, the best possible estimates of wave action
should be sent to HO. Tide observers should be familiar with reporting procedures in the
publication by,the Coast and Geodetic Survey (1970).

S. 3 C0104UNICATIONS

Before a tide station can he incorporated into the TWS, adequate communication
facilities must be available, on a basis of 24 hours a day. This is required because
tsunamis can strike at any time of the day or night and reliable fast communication
facilities must be immediately available. Because of advances being made in demand
telemetry, some of the tide stations added to the TWS in the future may not be manned 24
hours a day; however, the need for communications will remain.

In the case of stations located outside the United States or its possessions, the
agency involved must assume the cost of any commerical communications in the transmission of
messages to and from a U.S. or AFTN communication facility.

For testing the operation of the warning systeri, for keeping cormunication-operating
personnel familiar with the procedures for handling message traffic pertaining to the
system, for determining transmission times, for insuring that tide observers are familiar
with reporting methods, and for determining the length of time it takes the tide observer to
obtain a reading from his gage, dummy or test messages aresent monthly to all tide
observers. These messages require the observer to nark his record in accordance with
instructions in section 5- of the puhlication by the Coast and Geodetic Survey (1970) and
report the time and height of the mark and the time or receipt of the message from Honolulu
Observatory.

SECTION VI. DISSEMNATION OF TStNM41 WATCH ANT) WARNING INPOPMATION.

6.1 DISSEMINATION AGENCIES

Agencies desiring to receive tsunami watch and warning information from HO first must
meet several requirements.

6.1..l Selection of agency

In order to limit the number of agencies to be contacted in the event of a tsunami,
warnings generally are issued to only one agency in a country, territory, or administrative
area. This agency usually is appointed by the 'central government or administrative head of
the area concerned.

6.1.2 111arning plan

To insure the proper operation of the warning system, the agency designated to
receive tsunami warnings must s@bmit an outline to the National Weather Service showing how
warnings will be released to the local population. The outline must contain the names
and/or offices of the responsible administrators on both the central and local levels, the
means of communication io be used, and the methods for disseminating warnings to the local
population in the event of a tsunami. The outline also must include a procedure for
reaching at any hour the head of the dissemination agency or a responsible assistant.

6.1.3 Communications

Any dissemination agency *tside the United States or its possessions must accept
responsibility for arranging communications between the agency and the nearest U.S.
communication facility designated by the National Weather Service and for all communications
within its area of responsibility. The dissemination agency will pay all toll charges for
use of commercial facilities between its headquarters and the accepted U.S. facility.

6.1.4 Function

The dissemination agency provides the last vital link between the Tsunami Warning
System and the public, the ultimate user of the warning information. As such, the
dissemination agency must motivate the @ublic (by both education and, where possible, by
law) to take necessary and desired actions to protect life and property.

6.1.5 Duties and responsibilities

The dissemination agency and/or the governing body of areas subject to tsunami danger
has the continuing responsibility for educating the public as to the dangers of tsunamis and
for developing safety measures that must be taken to avoid loss of life and to reduce
property damage. The National Weather Service will cooperate as far as possible in making
available educational material for reproduction and distribution. Results of research
conducted by the Environmental Research Laboratories and others will be utilized by the
warning system and made available to interested scholars.

Responsible agencies should have well-developed emergency plans for all threatened
localities. These plans should delineate clearly areas of possible inundation. Evacuation
routes should be designated, and safe areas-should be marked. The amount of advance warning
necessary to insure evacuation from danger areas also should be known. Emergency duties and
responsibilities should be designated, and all affected officials should be thoroughly
familiar with their duties.

6.2 DISSEMINATION PROCEDURES

Tsunami watch and warning messages originate at Honolulu Observatory and are passed to
dissemination agencies over the circuits described in topic 9.2. When time is available,
the personnel of the dissenination agency evaluate the watch or warning and attempt to make
some estiriate of the probable impact of the disturbance. Stich procedures of the , emergency
plFin as are appropriate then are put into operation. Watch and warning information may be
passed (depending on the time and facilities availal@le) to the coastal population by any or
all of the following methods: radio, television, sirens, bells, whistles, warning flags,
mobile loud speakers, and personal contact.

6.3 WATCH MID WARNING INFnqj%Tlo@j

ilonolulu Observatory issues two basic types of bulletins--watch bulletins and warning
bulletins. Watch bulletins are issued when an earthquake has been detected which is of
sufficient magnitude and,in such a location that the generation of a tsunami is possible.
They normally will include Estimated Times of (tsunani).Arrival (ETA) at tide stations in
the warning system, if available and time permits.

Warnings are issued upon receipt by HO of positive evidence that a tsunami exists and
will contain estimated times of arrival at tide stations in the warning system. Bulletins
subsequent to the official warning message, designated Tsunami Warning Supplements, normally
will carry information on wave heights and other information as deemed appropriate by HO.
During an emergency, HO will not allow more than 1 hour to lapse between subsequent
bulletins. This policy will be adhered to even when no new data have @ecome available.

Watch and warning messages also will be issued from time to time by regional warning
systems. These watches and warnings will be directed specifically to the area served by the
regional system. The warnings issued by the regional warning systems usually are based on
seismic data only.

Because of the amount of time required to obtain confirmation of the existence of a
tsunami, warnings sometimes are delayed. Dissemination agencies should know how long in
advance of a tsunami they need to receive a warning so as to clear local populations from
areas likely to be affected. In the event that no warning is received before the beginning
of this period, the recommended course would be to treat the previously received watch
message as a warning and begin clearing danger areas. Dissemination agencies should take
into account the stage of the tide and weather conditions. when projecting expected tsunami
danger. A wave that would -cause no damage at low tide or on calm days could be highly
destructive during high tide, high surf, or local high wind conditions.

6.4 ALL-CLEAR AND CANCELLATION INFORMATION

At present, HO does not have enough data available to enable it to determine when
danger has passed for any given area. Local conditions can cause wide.variations in tsunami
wave action. Consequently, all clear determinations must be made by the local dissemination
agencies. - In general, if wave action occurs, action agencies shall assume all-clear status
when free from damaging waves for'2 hours unless additional ETAs have been announced by HO
or local conditions warrant the continuation of warning status. If no wave or only
insignificant waves occur, action.aBencies shall assume all-clear status 2 hours after the
latest ETA announced by Ito.

Honolulu Observatory occasionally will issue a watch or warning cancellation. Upon
receipt of such cancellations, action agencies immediately shall assume all-clear status.

A cancellation of a watch or warning must not be confused with an all-cleaT message. A
watch will be cancelled when HO determines that a wave has not been generated. A warning
will be cancelled if it is issued on the basis of erroneous data or if HO determines from
subsequent information that only an insignificant wave has been generated. In addition, a
warning nay be cancelled on a selective basis when a significant wave that has been.
generated clearly poses no threat to.one or more of the areas HO warns, either because of
intervening continents or islands which screen them or because the orientation of the
generating area causes the tsunami to be directed away from these areas.

APPE14DIX A. ALASKA REGIONAL TSUNAMI WARNING SYSTEM

ALI HISTORY

The Alaska,Regional Tsunami Warning System (ARTWS) was established as the result of
the great earthquake,occurring in the Prince William Sound area of Alaska on March 27, 1964
(Harch 28 GMT). This event alerted State and Federal officials to the need for a facility
to provide timely' and effective earthquake and tsunami information for Alaska and the
northern Pacific.

Funds were provided by Congress in 1965 to construct two new observatories and
establish a tsunami warning system in Alaska. The first observatory to be constructed was
.at the U.-S. Naval Station on Adak Island in the Andreanof I-slands. This Aleutian Chain
island is located 1,200 miles southwest of Anchorage. The city of Palmer in the Matanuska
Valley 40 miles north of Anchorage was selected as the site for the primary observatory.
Construction of the observatory installations, the task o f engineering and assembling the
data systems, and the hookup of the extensive telecommunication and data terlemetry network
was completed in the summer of 1967. With the dedication of the Palmer Observatory as the
Alaska Regional Tsunami. Warning Center on September 2, 1967, the ARTWS became operational.

A1.2 OBJECTIVES

The primary objective of the Alaska Regional Tsunami Warning System is to detect and
locate ma)or earthquakes in the Alaskan region and, in the event that tsunami generation is
possible or probable, provide timely and effective tsunami information and warnings to those
residents ;f Alaska and the Aleutian Islands likely to be affected.

A1.3 DESCRIPTION

The Palmer and Adak Observatories under the National Weather Service, Alaska Region,
operate the ARIUS. (See figure 5.) Data from the network of seismograph and tide stations
that make up the warning system are telemetered 'continuously to the Warning Center at
Palmer. The ARTWS basically consists of the 2 observatories, 17 remote satellite seismic
stations, and 8 tide-gage stations.
I
The system started with six remote seismic stations at Adak, Kodiak, Sitka, Arctic
Valley, Houston, and Gilmore Creek and a three-component short-period and a three-component
long-period system at Palmer. There were seven tide gages remoted to Palmer from Shemya,
Adak, Unalaska, Cold Bay, Kodiak, Seward, a nd Sitka.

To improve control and increase reliability and accuracy, 12 additional seismic
stations at Shemya, Nikolski, Pcrt Holler, Sparrevohn, Tatalina, Indian Mountain, Granite
Mountain, Black Rapids, Tolsona, Middleton Island, Fort Yukon, and Yakutat have been added
since 1967. The tide station at.Cold Bay was relocated to Sand Point, and an eighth tide
gage was installed at Yakutat and remoted to Palmer.

A1.4 OPERATIONS

As Warning Center of the ARTWS, Palmer Observatory detects, locates, and computes
magnitudes for major earthquakes in the northern Pacific region. Palmer Observatory also
determines if the magnitude and location is sufficient to generate a tsunami and issues
information or bulletins, as appropriate. The observatory has the responsibility to provide
vital tsunami watch and warning information for the coastal population of Alaska and tsunami
watch information for the coastal population of Washington, Oregon, California, and Canada.
(Note that update or cancellation messages for Washington, Oregon, California, and Canada
are issued from Honolulu, Hawaii.) Immediate earthquake information is furnished to the

159

International Tsunami Information Center in-flonolulu; the Japan Meteorological Agency in
Tokyo- and the National Earthquake Information Service in Boulder, Colorado. All the
co;I@Lcation channels available to the Palmer Observatory are shown in figure 6.

For utilizing the recorded data at Palmer with mininupi delay, expedient and precise
routine step-by-step formulalil-e methods have been developed to calculate epicenters and
nagnitudes. ' General procedures have been established for each situation and location to
provide the urgently needed tinely information to the affected or threatened areas.

A1.4.1 Earthquakles in the Alaskan coastal region

The Palmer Observatory Will issue a tsunami i,@atch for Alaskan coastal earthquakes of
magnitude 11, 6.75 to 7.0 and a tsunarii warning for events of greater magnitude. The area of
dissemination will be based on the location,and magnitude of the earthquake. (See topic
A1.4.3.)

After the tsunami watches or warnings are issued, Palmer will monitor the recorded
tsunami effects and issue cancellation, all-clear, or extension bulletins as appropriate.

When an earthquake of magnitude MS 7.0 or greater occurs within 300 kilometers from
Adak, Adak Observatory will issue an immediate tsunami warning for the area extending from
Anchit@a to Seguan Island. , Palmer Observatory extends, continues, or cancels tsunami
warnings issued by Adak Observatory.

Warnings issued by the Alaska Regional Tsunami Warning System normally will be based
on seismic data. Confirmation of the existence of a tsunami will be given as rapidly as
possible. If a tsunami exists, Palmer will be able to monitor its progress on the eight
widely spaced tide gages at Palmer. If a correction to the ETAs is indicated, it will be
made immediately and disseminated.

All bulletins will be t@pdated at least hourly. If negative or minor unusual tide
activity has been noted on the tide stations nearest the earthquake epicenter 30 minutes
after the ETAs, the watch or warning status may be cancelled. If a tsunami is generated,
.dissemination agencies will follow established all-clear procedures of the Tsunami Warning
System (i.e., all action agencies shall assume all-clear when free from damaging waves for 2
hours or 2 hours after ETA if no major waves are recordedj. Danger to navigation due to
rapid current fluctuations in channels and harbors may continue for several hours.

A1.4.2 Earthquakes outside the Alaskan region

If an earthquake with a magnitude of 11 s 7.5 or greater occurs in the Komandorski
Islands or along the east coast'of Kamchatka, Palmer Observatory immediately will issue a
watch for the western Aleutian Islands.

If an earthquake of magnitude 11 s 7.5 or greater occurs near the west coasts of Canada,
Washington, Oregon, or-California, the Palmer Observatory will issue an immediate tsunami
watch to the appropriate agencies in these areas.

The Honolulu Observatory will be responsible for upgrading, expanding, or canceling
any watches issued by the Palmer Observatory for regions outside Alaska. While Palmer
Observatory has no responsibility for issuing warnings for tsunamis generated outside
Alaskan waters, it will provide technical advice to Alaskan agencies during these
occurrences.
