A 7.0 earthquake struck off the coast of Northern California Thursday morning, triggering a tsunami warning for parts of the coastline that includes the San Francisco Bay Area.

The National Tsunami Warning Center issued an alert telling people in the affected region to move to higher ground. The warning extends from Florence, Oregon, to Davenport, California.

The quake struck about 40 miles west of Petrolia, a small unincorporated community in Humboldt County at 10:44 a.m. local time, according to the U.S. Geological Survey.

The Bay Area’s rapid transit network (BART) suspended service through the underwater tunnel that connects San Francisco and Oakland as a precaution.

People in the Bay Area reported on social media that there were building evacuations in process. The San Francisco Zoo said it was evacuating guests and securing animals before staff moved to high ground.

This is a developing story and will be updated when more information becomes available.
