A minor earthquake with a preliminary magnitude of 3.6 on the Richter scale shook parts of the Bay Area Saturday afternoon, the US Geological Survey reported.

A USGS reading of the 7:04 p.m. quake put the epicenter 2 miles southeast of Hercules in Contra Costa County.  

There were no immediate reports of damage in the surrounding area, but residents from Hayward to Vallejo reported that they felt the quick temblor.

BART stopped train service momentarily to conduct a visual inspection of tracks for damage, riders told the Beat. The inspections are part of the agency’s normal operating procedures following earthquakes.
