Officials across the continent’s West Coast are monitoring the effects of a magnitude 7.0 earthquake that hit off the coast of northern California, triggering a tsunami warning.
According to the U.S. National Weather Service, the quake, initially measured at magnitude 7.3 but later revised down, struck 72 kilometres southwest of Eureka, Calif., at a depth of 12 kilometres.
In response a tsunami warning has been issued for the Douglas/Lane Line area of Oregon and Davenport, Calif.
Emergency Info B.C. says it is monitoring for any potential threat to the province.
The quake struck at 10:44 a.m. PT west of Ferndale, a small city in coastal Humboldt County near the Oregon border, according to the U.S. Geological Survey (USGS).
It 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 Bay Area Rapid Transit District, known as BART, has stopped traffic in all directions through the underwater tunnel between San Francisco and Oakland.
At least 5.3 million people in California were under a tsunami warning after the earthquake, the USGS said in a yellow alert, which predicts localized but minimal damage.
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.”
