Plumas County Earthquake


On May 11 at 4:19 p.m. a 5.5 magnitude earthquake occurred in the Lake Almanor area near Chester in Plumas County. As soon as the shaking stopped, the California Governor’s Office of Emergency Services (Cal OES), along with its local, state and federal partners, swiftly jumped into action.

No substantial damage or significant injuries were immediately reported. Cal OES and its partners continue to inspect and monitor key infrastructure sites and public services such as health care facilities, dams and area roadways.

“Working with our scientific partners and the California Geological Survey, we stand at the ready,” said Jose Lara, Cal OES Seismic Hazards Branch program manager.

As many aftershocks have occurred, including a magnitude 5.2 in the same area about 12 hours after the initial quake, it is important for all Californians to remember to be earthquake ready.
