The earthquake was reported at 6:49 a.m. and was located 1 mile north of Piedmont and 3 miles southeast of Berkeley, USGS officials said.

The earthquake had a depth of 3.3 miles, according to USGS officials.

So far there have been no reports of major damages, but the jolt was felt throughout the Bay Area.

There have been several small aftershocks since the first quake. The largest was a 2.4 magnitude, reported about 7:40, according to the USGS.

Callers to KPIX 5 reported items falling from shelves and broken picture frames and glasses, but so far there was no report of injuries.

Apparently, one Tweeter’s animals felt it before she did. Her home surveillance video caught their reactions.

Residents have said it felt like two large jolts.

The quake was felt as far away as Vacaville.

BART trains were halted briefly as a precaution, but service has resumed.
