Magnitude 5.7 earthquake hits off northern California
A magnitude 5.7 earthquake struck on Friday off the coast of Northern California in the Pacific Ocean, the US Geological Survey (USGS) said, but there were no reports of damage or injury.
It was quickly followed by a second quake of 5.6 closer to shore, the USGS said. The larger temblor was initially reported by the agency as magnitude 5.8.
Both quakes struck west of the California town of Petrolia and were very shallow, amplifying their effects, but a USGS map showed that they were not widely felt along the coast.
