Another quake rumbles through Piedmont

An earthquake with a magnitude of 3.5 rumbled thorugh the East Bay Thursday morning, a day after a quake struck near Piedmont.

The USGS said the quake struck near Piedmont at 6:12 a.m.

On Wednesday, a quake with a magnitude of 3.4 also struck Piedmont at 4:42 a.m. As a result, BART trains were delayed as crews inspected the safety of the tracks. 

There were no immediate reports of damage.

But people in Alameda, Albany, Berkeley, Oakland, Orinda, Emeryville,  El Cerrito, Hayward, San Leandro, Walnut Creek, San Rafael, Daly City, Pacifica, San Francisco all tweeted that they felt it, noting that it felt a bit weaker than the one on Wednesday. 

Thursday is coincidentally the 25th anniversary of the Northridge earthquake in Southern California's San Fernando Valley, which killed dozens and caused $25 billion in damage.
