FERNDALE, Calif. (AP) — 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.

No injuries were immediately reported following the earthquake, which occurred about 2:34 a.m. near Ferndale, a small community about 213 miles (343 kilometers) northwest of San Francisco.

Following the earthquake, more than 55,000 customers were reported to be without power in the surrounding area, according to poweroutage.us, which tracks outages across the country.

That earthquake was centered in El Cerrito, about a 16-mile (25-kilometer) drive to downtown San Francisco.
