========================================================================= This is a preliminary UCB moment tensor solution for the event located 11 km S of Tres Pinos, CA (36.694N, 121.333W; Z=6.3km; ML4.1; USGS/UCB Joint Notification System) on July 2, 2001 at 17:33:53UTC. A Mw4.1 and depth of 11 km were obtained from long-period complete waveforms recorded at BDM, BKS, JRSC and MHC.
