An earthquake with a preliminary magnitude of 3.2 has rattled part of the San Francisco Bay area.
The US Geological Survey says the quake hit at 2:52 p.m. about three miles (five kilometers) southeast of downtown Berkeley. A police dispatcher says police hadn't received any reports of damage or injuries.
The quake follows a series of similar-sized temblors that shook the area last month. Two quakes on Oct. 20 one with a magnitude of 3.8 and another a magnitude 4.0 hit the same day that many Californians took part in an annual earthquake preparedness drill.
