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 Tuesday September 29 2009 at 10:48 AM (PDT) we recorded an earthquake (preliminary Mw 8.0) located in the Samoa Islands region, Pacific Ocean.
