A magnitude 6.4 earthquake rattled Northern California early Tuesday morning, causing widespread damage and leaving tens of thousands without power in Humboldt County.
The quake was reported at 2:34 a.m., about 7½ miles southwest of Ferndale, according to the U.S. Geological Survey. No tsunami was expected, the Humboldt County Sheriff’s Office said on Twitter, but the agency advised residents to prepare for aftershocks.
There have been dozens of aftershocks since the initial quake, according to the USGS, including a magnitude 4.6 shake 4½ miles northwest of Rio Dell.
