This is a preliminary UCB moment tensor solution for the event located
25 km E of Willits, CA (39.392N 123.067W; z=7km; ML=4.2; USGS/UCB
Joint Notification System) on May 17, 2000 at 22:32:07 (UTC). A Mw 4.5
and depth of 11 km were obtained from long-period waves recorded by
YBH, WDC, and HOPS.
Best Fitting Double-Couple:
Mo = 5.99E+22 Dyne-cm
Mw = 4.48
Z = 11 km
