This module is designed to help emergency managers prepare their communities for tsunamis. Lessons include basic tsunami science, hazards produced by tsunamis, regional U.S. tsunami risks, the tsunami warning system, the importance of public education activities, and how to craft good emergency messages and develop tsunami response plans. Additional content provides video interviews of lessons learned by public officials in Crescent City, CA after the March 11, 2011 tsunami that originated in Japan. The module also contains links to extensive Reference and Resources sections. The latter includes tsunami PowerPoint presentations for each major U.S. region (Atlantic Coast, Gulf Coast, West Coast, Hawaii, and Pacific Islands, Alaska, and the Caribbean) that can be downloaded and customized for a particular location or need.
