A magnitude-5.7 earthquake was reported early Wednesday afternoon off the Northern California coast.
The quake was centered about 25 miles southwest of Ferndale in Humboldt County. No tsunami alerts are expected after the quake, which occurred at about 1:10 p.m., according to a statement from the National Tsunami Warning Center.
Light to moderate shaking was reported in and near coastal communities, including Eureka and Fortuna. Earthquakes of magnitudes 2.6 and 3.3 were reported in the same location within about 20 minutes of the initial shaking.
There were no immediate reports of damage.
The Northern California coast is one of the most tsunami-prone regions in the continental United States. More than 30 tsunamis -- a series of ocean waves caused by displacements in the sea floor -- have been reported on the North Coast, five of which were damaging, according to Humboldt State University.
