The Anza group at the University of California San Diego operates a broadband seismograph network consisting of 14 (+ 2) three component broadband seismograph stations centered near Anza, California (see map).
On Tuesday, January 21nd, 2003 at 18:06 (PST) we recorded a quake (preliminary ml 7.60) located near Colima Mexico.
If you felt the quake, the USGS would like to know. Please add to the USGS "Did you feel it?" page.

Initial source parameters for the recent event and aftershocks are shown below. The epicentral distance (distance separating the epicenter and the closest station in the recording network) for Anza is 18.389 (2044 km).
This map shows the mainshock (red star) and any associated aftershocks (orange stars). Anza network stations are yellow triangles.

Of local interest:
We operate a broadband station on Mt. Soledad. At 18:06 (PST) station SOL recorded the P wave from this event. Here is a view of that event as picked by our analyst. The red P indicates a P wave arrival, the red S indicates an S wave arrival.
