The Anza group at the University of California San Diego operates a broadband seismograph network consisting of 13 (+ 2) three component broadband seismograph stations centered near Anza Californa (see map).

On Saturday February 10th, 2001 shortly after 13:05 PDT we recorded a quake (preliminary ml 5.1) located approximately 1 km to the W of the town of Big Bear.
