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 Sunday April 1 2007 at 1:39 PM (PDT) we recorded an earthquake (preliminary Mw 8.0) located near Gizo. A tsunami warning has been issued for the region. See the Pacific Tsunami Warning Center website's latest warning. See also the West Coast & Alaska Tsunami Warning Center website's latest warning.

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 10017 km (90.00 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 at the Santa Margarita Ecological Reserve. At 13:52 (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.
