Magnitude 5.6 Earthquake Shakes Northern California

A magnitude 5.6 earthquake struck Northern California early Wednesday, with shaking felt across the Redwood Valley area.

The Redwood Valley earthquake followed warnings issued in May by some experts that a future major California earthquake—often referred to as "The Big One"—could trigger cascading impacts across the West Coast.

The earthquake occurred at approximately 8:10 a.m. Pacific Time, according to the United States Geological Survey (USGS), Zain Khan reported for California Post.

California Gov. Gavin Newsom's office said it is monitoring the situation.

"Governor Newsom has been briefed on reports of an earthquake in Mendocino County. The Governor's Office is closely coordinating with emergency officials and assessing potential impacts and damage," the governor's office said in a post on X.

According to the USGS, at least 15 aftershocks were recorded following the main quake.

Pacific Gas and Electric Co. (PG&E) reported that thousands of customers in Willits and nearby communities temporarily lost electricity.

The Redwood Valley earthquake followed warnings issued in May by some experts that a future major California earthquake—often referred to as "The Big One"—could trigger cascading impacts across the West Coast.

Following Wednesday's earthquake, the National Weather Service and the US Tsunami Warning System said there was no tsunami threat.

"No tsunami warning, advisory, watch, or threat," the US Tsunami Warning System said.
