The U.S. Geological Survey said a magnitude 5.6 earthquake hit near the Pacific coast of Northern California.

The agency says the earthquake struck at 8:53 p.m. at a spot 17.3 miles (27.9 kilometers) southwest of Scotia, a town of 850 people.

The quake was hit 3 miles from Petrolia.

The earthquake had a depth of 5.6 miles.

Lostcoastoutpost.com reported a simultaneous 5.4 magnitude earthquake directly to the south off the coast of the King Range National Conservation Area. That tremor had an estimated depth of 4.3 miles, according to the Humboldt County local news website.

One local at the site commented that the quake could be felt for a “solid 10 seconds” and another said they felt a “pretty good shake in McKinleyville.”

Petrolia, in Humboldt County, has an estimated population of a few hundred people, and is located 253 miles north of San Francisco in a wilderness area that experiences frequent earthquake activity.

An average of five earthquakes with magnitudes between 5.0 and 6.0 occur annually in California and Nevada, according to a recent three-year data sample.
