Craig S. Weaver Paula K. Dunbar 2015 <p>The first U.S. Tsunami Hazard Assessment (Dunbar and Weaver, 2008) was prepared at the request of the National Tsunami Hazard Mitigation Program (NTHMP). The NTHMP is a partnership formed between federal and state agencies to reduce the impact of tsunamis through hazard assessment, warning guidance, and mitigation. The assessment was conducted in response to a 2005 joint report by the Sub-Committee on Disaster Reduction and the U.S. Group on Earth Observations entitled Tsunami Risk Reduction for the United States: A Framework for Action. The first specific action called for in the Framework was to &ldquo;develop standardized and coordinated tsunami hazard and risk assessments for all coastal regions of the United States and its territories.&rdquo; Since the first assessment, there have been a number of very significant tsunamis, including the 2009 Samoa, 2010 Chile, and 2011 Japan tsunamis. As a result, the NTHMP requested an update of the U.S. tsunami hazard assessment.</p> application/pdf en National Oceanic and Atmospheric Administration (NOAA) U.S. States and Territories National Tsunami Hazard Assessment: Historical record and sources for waves – Update reports
