Global view of quake

 

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 Saturday March 24 2007 at 4:41 PM (PST) we recorded an earthquake (preliminary Mw 6.7) located near Kanazawa.

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 9026 km (81.17 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.

This earthquake occurred within 2 minutes of a magnitude 7.2 earthquake near the Vanuatu Islands in the Pacific Ocean. Consequently, the waveforms recorded at Anza stations consist of both events, obscuring each individual event. In addition, a large aftershock from the Vanuatu region appears as a third P arrival. Please bear this in mind when studying the plots below.

We operate a broadband station on Mt. Soledad. At 16:54 (PST) station SOL 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.
