WC&ATWC; Most Recent Tsunami Message Page

NOTICE: This page is updated when a Tsunami Information Message or Tsunami Warning Message is issued. Tsunami Information messages are normally issued when smaller earthquakes (greater than magnitude 4.0, but less than 6.5) may be felt near coastal areas. These messages are issued to assure coastal residents and emergency managers that the earthquake was non-tsunamigenic.
If you are seeking information about an earthquake and there is NO information about that event on this page, then the magnitude of that earthquake was below the threshold for the issuance of a Tsunami Message for that area, or the information has been replaced with that of a more recent earthquake. Go to USGS Earthquakes or Earthquake Catalogs or Previous Messages to search for additional earthquake information.
