A magnitude 6.4 earthquake shook parts of Northern California early Tuesday, jolting people awake, the U.S. Geological Survey said, and thousands were without power afterward.

At least two people suffered fall-related injuries, local police said.

The earthquake occurred about 2:34 a.m. Pacific Time near Ferndale, a small community about 213 miles northwest of San Francisco.

Emergency officials say “widespread damages” have been reported to roads and homes throughout Humboldt County. PG&E says it has initiated its emergency response plan and crews are responding to gas and electric hazards.

Following the earthquake, more than 71,000 customers were reported to be without power in the surrounding area, according to poweroutage.us, which tracks outages across the country.

The earthquake came just days after a small magnitude 3.6 earthquake struck the San Francisco Bay Area, waking up thousands of people at 3:39 a.m. Saturday and causing minor damage.

That earthquake was centered in El Cerrito, about a 16-mile drive to downtown San Francisco.
