Progress in NTHMP Hazard Assessment

The Hazard Assessment component of the U.S. National Tsunami Hazard Mitigation Program has completed 22 modeling efforts covering 113 coastal communities with an estimated population of 1.2 million residents that are at risk. Twenty-three evacuation maps have also been completed. Important improvements in organizational structure have been made with the addition of two State geotechnical agency representatives to Steering Group membership, and progress has been made on other improvements suggested by program reviewers.

Program aims to reduce impact of tsunamis on Pacific states

A state/federal partnership is underway to lessen the impact of tsunamis in U.S. communities along the Pacific Ocean. Now in its second year, the National Tsunami Hazard Mitigation Program is continuing to prepare tsunami inundation maps, construct deepocean tsunami detectors, upgrade seismic networks, and develop mitigation plans for each state along the Pacific coast. Goals include providing early warning of tsunamis and educating residents about evacuation.Coastal communities in Alaska, northern California, southeastern Hawaii, Oregon, and Washington are particularly threatened by tsunamis generated by local earthquakes. For example, there is mounting geological and seismological evidence that a number of large, local earthquakes in the past 2000 years generated tsunamis resulting in sudden and extensive flooding along the coastlines of Washington, Oregon, and California [Clague, 1997]. The earthquake zones shown in Figure 1 subject all five Pacific states to local tsunami threat. These zones and other seismically active areas of the Pacific rim also expose these states to distant tsunami hazard.
