This is a preliminary UCB moment tensor solution for the event 18 km
E of San Jose (37.3N 121.7W; Z=8 km; ML=4.4; USGS/UCB JOint Notification
System) on February 25, 2001 at 23:18UTC. A Mw4.4 and depth of 11 km were
obtained from long period waves recorded by BDM, JRSC, and SAO.
 
 Best Fitting Double-Couple:
    Mo = 4.22E+22 Dyne-cm
