The Anza group at the University of California San Diego operates a broadband seismograph network consisting of 17 three component broadband seismograph stations centered near Anza, California (see map).
On Thursday May 23 2013 at 10:44 PM (PDT) we recorded an earthquake (preliminary mw 8.3) located within the Sea of Okhotsk.
If you have felt this quake, the USGS would like to know. Please add your comments to the USGS page "Did you feel it?".

Initial source parameters for this tremor are indicated below. The epicentral distance (i.e. the distance separating the epicenter and the closest station in the recording network) for Anza is 6949 km (62.53 degrees).
This map shows the mainshock as a red star. Associated aftershocks are orange stars. Anza network stations are yellow triangles. Blue lines are major rivers. Thin black lines are state boundaries and thick black lines are national boundaries.

Of local interest
We operate a broadband station at the Santa Margarita Ecological Reserve. At 22:54 (PDT) station SMER recorded the P wave from this event. Here is a view of that event as picked by our analyst. A red P indicates a P wave arrival, a red S indicates an S wave arrival.
