San Francisco Bay Area Earthquake 2012: Minor Tremor Shakes Region

Quake Shakes San Francisco

A magnitude 4.0 earthquake shook the San Francisco Bay Area early Monday morning, according to information from the United States Geological Survey.

According to the Associated Press, no damage has been reported, although Twitter users in the region reported being woken up by the tremor.

The earthquake's epicenter was one mile from El Cerrito, just east of Richmond and about ten miles north of Oakland, the USGS reports. Initially, the quake -- which struck at 5:33 a.m. PST -- was reported to have occurred at a depth of 5.5 miles, though that number was later revised to 5.7 miles.

This is a developing story. Check back for updates.

Correction: A previous update to this article incorrectly stated the earthquake had been downgraded to a 2.9 magnitude.
