A magnitude 3.5 earthquake shook buildings in Oakland, California, Monday night, according to the United States Geological Survey (USGS). The Reuters news agency reports there were no immediate signs of damage or injury.
USGS says the quake hit about 1.8 miles east-northeast of Oakland -- a city on the east side of San Francisco Bay.
CBS San Fransciso writes that it struck around 7:18 p.m. local time.
An initial magnitude of 3.8 was reported, but was later downgraded by USGS.
Officials from the San Francisco BART train service said that it temporarily held trains during the "seismic event" to inspect tracks. Service then resumed with a 10 minute delay.
