SAN FRANCISCO (CBS SF/AP) — A preliminary magnitude 4.5 earthquake shook San Francisco Bay Area residents out of their slumber early Thursday morning.

The U.S. Geological Survey says the quake’s epicenter was 2 miles from Berkeley. The earthquake had a preliminary depth of 8 miles.

The quake struck at 2:39 a.m. and was felt throughout the East Bay, North Bay and San Francisco. While many were jolted out of their beds, there was no preliminary reports of major damage or injuries.

Bay Area Rapid Transit said it had checked tracks for damage and found no problems. Early delays in train service were cleared up by 5:30 a.m., the agency said.

Jack Boatwright, a geophysicist with the USGS Earthquake Science Center in Menlo Park, said the shaking from the quake “seemed a little weak, about half as strong as what you would expect.”

He told the San Francisco Chronicle that by 4:15 a.m., there had been no aftershocks, which he called “a good sign. It may mean less likelihood of a larger earthquake to follow.”

The quake did knock items off the 24-hour Safeway’s shelves in San Leandro.

The USGS website says people reported feeling the quake 40 miles south in San Jose.
