– Earthquake Swarm Hits Monterey County; Will A Big One Hit San Francisco?
A 4.6-magnitude earthquake rattled Monterey County on Monday and was felt more than 90 miles away in San Francisco, officials said. The quake hit at 11:31 a.m. about 13 miles northeast of Gonzales, near Salinas, and was followed by nine smaller aftershocks, with the largest measuring magnitude 2.8, said Annemarie Baltay, a seismologist with the U.S. Geological Survey in Menlo Park. There were no reports of injuries or damage. Baltay said the quake occurred on the San Andreas Fault, close to an area where the Calaveras Fault branches off. The quake happened at a depth of about 4 miles.
