This study examined factors that influence the extent to which people prepare for tsunamis and how they respond to different tsunami warnings. In each community, residents were asked about their experiences, attitudes, and knowledge with regard to tsunamis. Led by researchers at the University of Hawaii and Mississippi State University, the project team consisted of researchers from the U.S., New Zealand, and Australia. Study sites included communities in 8 states and territories (Alaska, Washington, Oregon, California, North Carolina, Puerto Rico, Florida, and Hawaii). Findings were to be used to inform policy decisions and develop and assess tsunami education and awareness programs.
