The National Oceanic and Atmospheric Administration (NOAA) leads U.S. detection and warning efforts and partners with federal and state agencies in the National Tsunami Hazard Mitigation Program (NTHMP) to reduce tsunami risks. In 2005, Congress appropriated $17.24 million in supplemental funding to enhance these efforts. This report (1) identifies U.S. coastal areas facing the greatest tsunami hazard and the extent to which potential impacts have been assessed, (2) discusses the effectiveness of the existing federal tsunami warning system, (3) describes efforts to mitigate the potential impacts of tsunamis on coastal communities, and (4) assesses NOAA's efforts to develop long-range plans for federal tsunami programs. https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-06-519/html/GAOREPORTS-GAO-06-519.htm https://www.govinfo.gov/content/pkg/GAOREPORTS-GAO-06-519/pdf/GAOREPORTS-GAO-06-519.pdf GAO-06-519 https://www.govinfo.gov/app/details/GAOREPORTS-GAO-06-519 Other Written Product GAO-06-519; U.S. Tsunami Preparedness: Federal and State Partners Collaborate to Help Communities Reduce Potential Impacts, but Significant Challenges Remain; Disaster planning Emergency management Emergency preparedness Intergovernmental relations Tsunamis Warning systems Weather forecasting Risk assessment Alaska California Hawaii Indian Ocean Tsunami National Tsunami Hazard Mitigation Program Public Law 109-13
