SAN RAMON, Calif. (AP) - Authorities say an earthquake has jolted the San Francisco Bay Area, making it at least the sixth small quake to hit the area within a week.
The U.S. Geological Survey says the quake with a preliminary 3.4 magnitude struck along the Calaveras Fault near the East Bay communities of San Ramon and Danville around 9:30 a.m. Wednesday.
USGS spokeswoman Leslie Gordon says the quake caused "weak to light shaking" in the area that could also be felt in other neighboring cities.
San Ramon Police say there have been no initial reports of damage or injuries.
USGS geologist David Schwartz says it was at least the sixth small quake to strike in and around San Ramon since Friday. He says the quakes have been about a mile apart from each other.
