Several earthquakes with epicenters beneath the ocean surface rattled the Northern California coastline early Monday.
The quakes occurred off the shore of Humboldt County and were all located roughly 24 to 29 miles southwest of the Northern California city of Ferndale, according to the U.S. Geological Survey.
The U.S.G.S. reported that the first quake occurred about 1:17 a.m. More quakes occurred over the next few hours.
The largest of the swarm of quakes had a 4.6 magnitude, according to the Geological Survey. This was the first of the shakers on Monday.
The strongest quake was felt in several communities, including Eureka, Ferndale, Fortuna, Rio Dell, Scotia, Garberville, Petrolia, Piercy and Alderpoint, according to a post on the U.S.G.S. website.
No injuries or damage were immediately reported as a result of the quakes.
The quakes occurred on or next to the San Andreas Fault, the U.S. Geological Survey webpage shows.
