San Francisco Bay Area residents were shaken out of their slumber by a magnitude 4.4 earthquake that was felt over a wide area but caused no major damage early Thursday.
The quake struck at 2:39 a.m. about 2 miles (3 kilometers) from Berkeley, just across the bay from San Francisco, according to the U.S. Geological Survey. The magnitude was revised after it was initially reported as magnitude 4.5. It happened at a depth of 8 miles (13 kilometers).
Social media posts showed people were awakened some 40 miles (64 kilometers) to the north and south, but there were no immediate reports of damage or injuries.
