This is a preliminary UCB moment tensor solution for the event
located 48 km SE of S. Lake Tahoe (38.646N 119.576W; z=4.5km; ML=4.8;
USGS/UCB Joint Notification System) on September 26, 2000 at 07:20:29UTC.
A Mw4.5 and depth of 8 km were obtained from long-period waves recorded
by BKS, CMB, POTR.
Best Fitting Double-Couple:
Mo = 6.15E+22 Dyne-cm
Mw = 4.49
Z = 8 km
