Two earthquakes centered near San Simeon shake North Coast

Two offshore earthquakes hit the North Coast on Thursday morning, a magnitude-4.2 quake at 11:42 a.m. and a magnitude-2.8 temblor five minutes later. But no damage was reported.

According to the U.S. Geological Survey, the epicenters of the quakes were about nine miles southwest of San Simeon. They occurred at a depth of about two miles.

There was “just some rattling,” but no damage from the quakes at Hearst Castle, said Nick Franco, State Parks district superintendent. The San Luis Obispo County Sheriff’s Office didn’t receive any reports of damage, either.

Terri Lee Guthrie said she felt the quake while working the front desk at Cambria Landing Inn and Suites in Cambria, 11 miles from the epicenter.

“My associate was sitting in a chair, and the chair shook, and I felt the ground move, and there was a flower arrangement and it moved around. We looked at each other and said, ‘Was that an earthquake?’ ” Guthrie said.

The earthquake was not felt at the Diablo Canyon nuclear power plant farther down the coast in Avila, said Tom Cuddy, a spokesman for PG&E.

The small quake “is a reminder that we do live in earthquake country and we should all be prepared for a damaging earthquake at any time,” the San Luis Obispo County Office of Emergency Services said a statement.
