Tsunami Warning Centers

NOAA's two tsunami warning centers are staffed 24 hours a day, 7 days a week. The main mission of the warning centers is to help protect life and property from tsunamis. To do this, warning center staff monitor for tsunamis and the earthquakes that may cause them, forecast tsunami impacts, issue tsunami messages, conduct public outreach and coordinate with partners to continually improve warning operations.

The National Tsunami Warning Center serves the continental United States, Alaska and Canada. The Pacific Tsunami Warning Center directly serves the Hawaiian Islands, the U.S. Pacific and Caribbean territories and the British Virgin Islands and is the primary international forecast center for the Pacific and Caribbean Basins.
