SAN FRANCISCO, Approx. – A magnitude 7.0 earthquake off the coast of Northern California has triggered a rare tsunami warning for coastal areas near the California-Oregon state line, including San Francisco Bay.

According to the US Geological Survey, a strong 7.0 magnitude earthquake was recorded around 10:44 a.m. PT about 60 miles off the coast of Ferndale, California. The USGS originally reported a magnitude 5.8 quake in Cobb, California, three minutes after the magnitude 7.0 quake, but has since updated its data to reduce the quake to a magnitude 2.5.

The powerful quake prompted a tsunami warning from Davenport to 10 miles south of Florence, Oregon. The warning remains in effect until further notice.

“If you are in this coastal area, move inland to higher ground,” the National Weather Service warning read.

A magnitude 7.0 earthquake struck Northern California on December 5, 2024.

A tsunami warning means that a tsunami with significant flooding is possible or is already occurring.

A tsunami is a series of long waves caused by significant disturbances in the ocean, most commonly earthquakes along the boundaries of tectonic plates.

“You are in danger”: Residents are urged to seek higher ground

The tremors of the severe earthquake were felt in Napa Valley and throughout San Francisco.

Emergency management in San Francisco warned residents: “You are in danger. Stay away from coastal waters.”

Bay Area Rapid Transportation (BART) suspended Transbay subway service to and from San Francisco following the earthquake.
