. This is a preliminary UCB moment tensor solution for the event
located California-Nevada border region (37.39N 117.07W; Z=5km; Mb=5.6;
NEIC) on August 1, 1999 at 16:06:22UTC. A Mw5.7 and depth of 8 km
were obtained from long-period waves recorded by CMB, KCC and PKD.
Best Fitting Double-Couple:
Mo = 3.61E+24 Dyne-cm
Mw = 5.67
Z = 8 km
Plane Strike Rake Dip
NP1 226 -87 64
NP2 39 -96 26
Principal Axes:
