Two earthquakes shook northern California early Sunday but local officials said there were no immediate reports of injuries or damages.
A magnitude 4.6 quake occurred about 19 miles west of Petrolia, California, according to the U.S. Geological Survey. The town is about 265 miles north of San Francisco. The quake hit at 2:26 a.m. PST (0926 GMT) and was 11 miles deep, according to the USGS National Earthquake Center.
A second quake struck the same location about a minute later, the center said in a revised report. USGS originally reported that the second quake, measuring 4.1, hit near Fort Ross, California.
Police counties said they had not received reports of damage or injuries.
