SEISMOLOGY:
Did One California Jolt Bring on Another?

Last weekend's Hector Mine earthquake, which struck the desert 160 kilometers northeast of Los Angeles, seems to support the idea that faults feel what happens to their neighbors. The magnitude 7.1 temblor--which did minimal damage because of its remote location--appears to have been triggered by stress transferred by the magnitude 7.3 Landers quake of 1992, which struck 160 kilometers to the east of Los Angeles.
