Logo Recent Earthquakes in Pacific Northwest

All Earthquakes on Index Map

Earthquakes recorded by the Pacific Northwest Seismograph Network during the past two weeks. Times are local (PST or PDT). Most recent earthquakes are at the top of the list. Click on the word "map" or "MAP" to see a map view. Click on a "DATE" to get additional text information. Magnitude 3 and greater earthquakes are printed in bold type. The top three magnitudes greater than or equal to 3 are in red. Earthquake locations are not being updated currently, although seismicity is continuing at Mount St Helens

Automatically calculated locations and magnitudes for Mount St. Helens events were inaccurate due to the continuous nature of the activity, so we have suspended posting of automatic locations in the MSH area. Analysts are going through the recorded data systematically and event locations will be posted as they become available. Our efforts are directed toward interpretation of data, in a rapidly evolving situation, rather than rapid posting of individual events.

Please see the Volcanic Advisory for updates.
