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 Wednesday September 30 2009 at 3:16 AM (PDT) we recorded an earthquake (preliminary Mw 7.6) located in southern Sumatra, Indonesia.
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 14671 km (131.82 degrees).
This map shows the mainshock as a red star. Associated aftershocks are orange stars. Anza network stations are yellow triangles. Gray lines are major rivers.

We operate a broadband station on Mt. Soledad. At 03:35 (PDT) station SOL recorded the PKiKP 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.
