A very strong earthquake rattled the Northern California coast and was widely felt across the region, but authorities said early Monday that there were no reports of any injuries or damages.
The magnitude 6.9 quake struck at 10:18 p.m. local time Sunday and was centred 50 miles (80 kilometres) west of Eureka and about four miles (six kilometres) beneath the Pacific seabed, according to the U.S. Geological Survey. It was followed by about a half-dozen aftershocks, including one of magnitude 4.6.
The quake was felt widely across the region but both fire and sheriff's officials in Humboldt County, which includes most of the populated areas near the epicenter, said early Monday more than four hours after the quake hit that they had no reports of any damage or injuries.
The National Tsunami Warning Center said there was no tsunami danger for the region.
But more than 3,000 people, including some in Oregon, reported on the USGS website that they felt the quake. Some reported a long, rolling shake that woke children or knocked items off shelves.
"This lasted longer than any earthquake I've ever felt," Raquel Maytorena, 52, who lives about a mile from the coast in Ferndale near Eureka, told The Los Angeles Times. "It just kept going and going, very slowly and softly. It was not violent. It almost felt like you were in a boat that was rocking."
