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, June 16, 2005 at 11:21 PM (PDT) we recorded a quake (preliminary Mw 6.4) located off the coast of Northern California.
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 are shown below. The epicentral distance (distance separating the epicenter and the closest station in the recording network) for Anza is 1158 km (10.41 degrees).
This map shows the mainshock (red star) and any associated aftershocks (orange stars). Anza network stations are yellow triangles.
Zoomed in Event Map
The map below is a higher resolution map of just the Northern California coast. Today's main shock (red star) and aftershocks (orange stars) are plotted alongside the June 14 2005 magnitude 7.0 event (large bright green star) and its respective aftershocks (smaller pale green stars). The closest cities in California are also plotted (Crescent City and Eureka).
Main shock in red, aftershocks in orange.

Of local interest:
We operate a broadband station on Mt. Soledad. At 23:24 (PDT) 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.
