A 7.0 magnitude earthquake hit the northern part of California Thursday, the US Geological Survey said.
It was centred in Petrolia in Humboldt County and followed by a tsunami warning.
A tsunami warning was issued for coastal California, including San Francisco, as well as Oregon. The National Tsunami Warning Center said it will be in effect from Davenport, California, to the border with Oregon until further notice.
At least 5.3 million people were under the tsunami warning.
The quake was felt in the Bay Area, and residents there were advised to move away from the coast after the tsunami warning.
Residents in San Francisco reported feeling a rolling motion for several seconds, followed by smaller aftershocks.
There were no immediate reports of any quake damage.
People were evacuated from the San Francisco Zoo and animals there are being moved to higher ground.
The BART transit system in the Bay Area was delayed in all directions as commuters were told to seek other transportation means.
The National Weather Service in Santa Cruz warned, “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.” (UPI)
