BOLINAS, Calif. — A moderate earthquake with a preliminary magnitude of 5.0 rocked this Northern California town Tuesday evening, rocking office buildings in San Francisco and rattling homes as far south as San Jose.

The quake happened at 5:06 p.m. PDT near the San Andreas Fault about 10 miles southwest of San Rafael, said U.S. Geological Survey spokesman Dale Cox.

No injuries or damage were immediately reported.

The quake rocked cars and made streetlights swing in San Francisco's Sunset district. Items fell off shelves, and as far south as El Granada, people said it felt like a heavy truck rumbling by.

Chris Lemmon, a clerk at a 7-11 convenience store in San Francisco, said he didn't notice the quake, but some of his customers did.

"A guy who lives a block away was telling me how much his building shook," Lemmon said. "He lives in an older building."

A few streets away at a 76 gas station, assistant manager Graham Church he definitely felt the quake.

"It was very quick, five or six seconds at the most," he said. "It was pretty sharp, pretty severe."
