HOLLISTER, Calif. (AP) - A magnitude-4.8 earthquake has struck a wilderness area of central California.
The U.S. Geological Survey says the temblor occurred at 12:42 p.m. Tuesday and was centered about 16 miles (25 kilometers) southeast of Hollister. The quake occurred at a depth of 6 miles (9.6 kilometers).
The epicenter area is in a rugged mountain range, with agricultural areas to the west.
Late Monday, the San Francisco Bay Area was rattled by a magnitude 4.5 earthquake.
That quake was center near Pleasant Hill, northeast of Oakland but was felt widely.
More than 67,000 people posted to the U.S. Geological Survey's citizen reporting web page.
Veteran seismologist Lucy Jones says the two quakes are too far apart to be related.
SAN FRANCISCO, Calif. - San Francisco also felt a magnitude 4.5 earthquake.
The Los Angeles Times reports moderate shaking was felt at 10:33 p.m. on Monday, with the epicenter the Pleasant Hill and Walnut Creek areas.
The U.S. Geological Survey says weak shaking was felt in San Francisco, Oakland and San Jose. Scientists say they don't expect any major structural damage.
Keith Knudsen, USGS geologist and deputy director of the agency's Earthquake Science Center, told the Times that the earthquake had a preliminary depth of about 9 miles (14 kilometers) underneath the surface, fairly deep for this part of the world.
Assistant Chief Chris Bachman of the Contra Costa County Fire Protection District said that as of about 11 p.m. Monday, there were no reports of injuries or property damage related to the earthquake.
