Live Tsunami Warnings
Official tsunami warnings, advisories and threat messages from NOAA’s tsunami warning centers, alongside the earthquakes that triggered them.
Where this data comes from
- NOAA National and Pacific Tsunami Warning Centers (tsunami.gov)
- USGS and EMSC earthquakes
Official alerts are shown exactly as issued and graded SEV-1 (extreme) to SEV-4 (minor). Each event shows its sources, how many independent feeds confirm it, and when it was received. About our data.
Frequently asked questions
Is there a tsunami warning right now?
Any active official tsunami message appears at the top of the live map as a breaking event.
What are the natural warning signs of a tsunami?
Strong or long shaking near the coast, a sudden fall or rise in sea level, or a loud roar from the ocean. Move inland or uphill at once without waiting for an official warning.
