Briefing reporters on his administration's response to Thursday's 7.0 earthquake in Humboldt County, Calif., Gov. Gavin Newsom said he was "concerned" about possible damage in Northern California.

Newsom, who was in San Diego to speak on transnational commerce at the U.S.-Mexico border, noted that a tsunami warning had been lifted, adding, "We're concerned about damage, particularly in the northern part of this state."

Newsom said he signed a state emergency declaration "that will allow us to provide more resources" as needed.

The governor did not note any specific damage caused by the earthquake and its many aftershocks, saying "early damage assessments are being made."

Aftershocks of Thursday's 7.0 earthquake off the Northern California coast continue to be felt by local residents.

While the initial quake struck at 10:44 a.m. PT 7 miles west-southwest of Ferndale, the USGS has since measured 32 aftershocks as of 1:15 p.m. PT. The aftershocks have ranged in intensity from a 4.3 quake near the original epicenter to one measuring just 2.5 on the Richter scale.

After receiving two separate emergency alerts on cellphones directing Bay Area residents to "move to high ground or inland now," some residents of the East Bay, which includes Oakland, Alameda, Berkeley, Albany, El Cerrito and Richmond (including this reporter) headed for the top of Albany Hill, which rises 338 feet from the edge of San Francisco Bay.

Some brought pet cats and dogs in their cars. Others pushed baby strollers on foot.

But no sooner had many arrived at a parking lot at the entrance to a public park on the hill when a third alert informed them that the tsunami warning had been lifted.

"It is safe to return home," the alert read.

The Berkeley, Calif., Police Department lifted the evacuation order for West Berkeley about 30 minutes after it has been issued.

The San Francisco Zoo, which is located in the western part of San Francisco, just blocks from the ocean, said in a statement that it was closing due to the tsunami warning.

"Guests have been evacuated and staff have moved to higher ground," the zoo said in a message posted to X.

It was not immediately clear when the zoo would reopen.

The National Weather Service has canceled the tsunami warnings it had issued for parts of Oregon and California following a strong earthquake that struck off the Northern California coast:

...THE TSUNAMI WARNING IS CANCELLED...

* The Tsunami Warning is canceled for the coastal areas of California and Oregon

OBSERVATIONS OF TSUNAMI ACTIVITY

* No tsunami observations are available to report.

"No tsunami danger exists for the U.S. west coast, British Columbia and Alaska," the weather service added.

In a statement, California Gov. Gavin Newsom's office said he has been briefed and is meeting with state emergency officials.

The National Weather Service issued a tsunami warning for parts of Oregon and California on Thursday after a powerful earthquake struck off the coast of Northern California.

According to the U.S. Geological Survey, the 7. magnitude earthquake was detected 45 miles southwest of Eureka, Calif., at a depth of 8 miles.
