West Coast and Alaska Tsunami Warning Center

This site is the homepage of the National Oceanic and Atmospheric Administration's (NOAA) tsunami warning center for Alaska and the west coast of the United States. Users can access current tsunami information through an interactive map that shows the latest events and information statements. Rolling over the map symbols provides the date and time, location, and preliminary magnitude of earthquakes. Clicking on them provides access to additional information, including a statement of whether a tsunami is expected. There are also links to previous warning messages, Really Simple Syndication (RSS) feeds with headlines, links to documents and brief information; publications; and links to related sites with additional information.
