A small earthquake rattled the the East Bay early Thursday, but there were no immediate reports of any problems.
The U.S. Geological Survey says the magnitude 3.6 temblor struck at 12:06 a.m. and was centered near San Ramon and about 15 miles east of San Francisco. The quake occurred 6 miles underground. It was first reported as a 3.5.
The Contra Costa County Sheriff’s office said it had no reports of any injuries or damages from the quake.
The USGS website had hundreds of hits from people in the Bay Area saying they felt it. On NBC Bay Area's Facebook page, several East Bay residents said they felt it. "Hell ya, in Castro Valley," Josef de la Vega wrote. Others felt it in Dublin, Hayward, Walnut Creek and Martinez.
