FERNDALE — A large earthquake with a magnitude of 6.4 jolted the Northern California coastline near Eureka Tuesday morning, the U.S. Geological Survey reported.
The earthquake occurred around 2:34 a.m. on Tuesday with the epicenter reported to be just offshore of Humboldt County in California.
Besides Eureka, the towns of Ferndale and Fortuna are nearby, based on the epicenter reported by the U.S. Geological Survey. The popular Humboldt Redwoods State Park is also in the vicinity.
A swarm of aftershocks that included a 4.6 magnitude shaker in the town of Rio Dell several miles inland from the coast also rumbled through Humboldt County Tuesday morning.
At least 13 aftershocks were reported by the U.S. Geological Survey within 45 minutes after the initial 6.4 quake. The aftershocks were primarily inland east of the original temblor.
The ShakeAlert app woke up Bay Area residents of a quake nearby, although that wasn’t the case.
A tsunami risk was ruled out by the National Weather Service. The Weather Service estimated that the quake occurred at a depth of one mile.
