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 Wednesday September 12 2007 at 4:49 PM (PDT) we recorded an earthquake (preliminary Mw 7.9) located in the Kepulauan Mentawai Region, Sumatra.
