Magnitude 5.2 quake near Napa

Last updated: 2014-10-13 21:29:07 UTC

The Anza group at the University of California San Diego operates a broadband seismograph network consisting of 13 (+ 2) three component broadband seismograph stations centered near Anza Californa (see map).

If you did feel the quake, USGS would like to know. Add to the USGS "Did you feel it?" page.

On Sunday September 3rd, 2000 shortly after 01:36 PDT we recorded a quake (preliminary ml 5.2) located approximately 14 km to the NW of the town of Napa.

The epicentral distance (distance separating the epicenter and the recording network) is ~6.77 degrees (752km). This quake is considered to be a "regional" event based on the epicentral distance.
