A 6.4-magnitude earthquake shook Northern California about 12 miles west of Ferndale at 2:34 a.m. local time, according to the United States Geological Survey.
By 3:30 a.m., poweroutage.us reported that about 60,000 customers in Humboldt County, about 60 percent of the total customers there, were without power. The oceanside county is more than 200 miles north of San Francisco.
On social media, the Humboldt County Sheriff’s Office asked people to avoid calling 911 unless they were experiencing an immediate emergency.
Caroline Titus, a journalist in Ferndale, posted a photo on Twitter showing items in her home spread across the floor after apparently falling off a shelf. “House is a mess,” she said.
The earthquake came exactly one year after a 6.2-magnitude quake struck in nearby Cape Mendocino, also in Humboldt County.
The National Weather Center said no tsunami was expected.
