LIVE: Magnitude 7.0 earthquake strikes Northern California, USGS reports; tsunami warning canceled

SAN FRANCISCO (KGO) — USGS says that a magnitude 7.0 earthquake has hit Northern California in Humboldt County.

The epicenter is off the coast near Petrolia, in Humboldt County, the USGS said.

Also, a tsunami warning that had been issued for coastal areas in California and Oregon, including San Francisco, was canceled just before noon local time.

“The tsunami Warning is canceled for the coastal areas of California and Oregon,” the National Tsunami Warning Center wrote on X. “No tsunami danger presently exists for this area.”

At least 5.3 million people in California were under the tsunami warning, the U.S. Geological Survey said in a yellow alert, which predicted localized but minimal damage.

The warning had been in effect from Davenport, California, to Douglas/Lane Line Oregon, the National Tsunami Warning Center said.

The earthquake was initially reported as a 6.6 quake but then was upgraded by USGS.

It was reported at 10:44 a.m. local time, according to the National Tsunami Warning Center.

Subsequent earthquakes were reported in the region, including a 5.0 magnitude near Ferndale and a 4.2 magnitude near Petrolia, according to the USGS.

Shake alerts in the USGS’s earthquake early warning system were delivered as far north as Lincoln City, Oregon, and as far south as Salinas, California, the agency said.

“System was activated and performed as designed. Still trying to ascertain how much warning people received,” the USGS said.

There were no immediate reports of any damage.

The earthquake was felt as far south as San Francisco, where residents felt a rolling motion for several seconds. It was followed by smaller aftershocks.

The San Francisco Zoo announced that guests have been evacuated and animals and staff are moving to higher ground after a Tsunami Warning was issued due to the quake in Humboldt County.

There is a major delay in the Bay Area’s BART transportation system due to the quake. There’s no train service though the underwater Transbay Tube.

California Gov. Gavin Newsom said officials with the state’s Office of Emergency Services are “actively responding to the earthquakes this morning in Northern California.”

“Californians should follow guidance from local emergency responders,” he said on social media.

Regarding aftershocks, there is currently a 5% chance of a magnitude 6 or larger earthquake occurring in the next week, and a 34% chance of a magnitude 5 quake occurring in that time frame, the USGS said.

More than 1.3 million people lived close enough to the quake that they could have felt it, the USGS estimated.

In the Santa Cruz area, phones buzzed with a tsunami warning from the National Weather Service that said: “A series of powerful waves and strong currents may impact coasts near you. You are in danger. Get away from coastal waters. Move to high ground or inland now. Keep away from the coast until local officials say it is safe to return.”
