A 7.0 magnitude earthquake struck off the Northern California coast in Humboldt County Thursday morning.
The epicenter was about 130 miles south of the Oregon border, with tremors felt as far as San Francisco, 270 miles away. A tsunami warning was issued for 5.3 million residents along the coast but was later canceled.
The quake caused minor damage in Humboldt County, including cracked roads and power outages affecting 10,000 residents. Over 30 aftershocks followed, the largest at 4.3 magnitude.
Gov. Gavin Newsom declared a state of emergency to assist recovery efforts.
