Geologist Predicts Southern California Earthquakes

A detailed analysis of two periods of past quake activity on a section of the fault suggests a drawn-out period of little seismic activity may be coming to an end, said University of Oregon geologist Ray Weldon... An earthquake on the southern San Andreas of magnitude-7.5 or larger could kill thousands of people in the greater Los Angeles area and cause damage estimated in the tens of billions of dollars."
