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.
