A powerful 7.0 magnitude earthquake struck Thursday off the coast of California, triggering a tsunami warning, U.S. seismologists reported.
The quake occurred at a depth of just 10 kilometers (6 miles), approximately 100 kilometers west-southwest of Ferndale, according to the United States Geological Survey.
“Based on preliminary earthquake parameters… hazardous tsunami are possible for coasts located within 300 KM of the earthquake epicenter,” said a warning issued by the National Weather Service’s Tsunami Warning Center in Honolulu.
The warning noted that no areas had yet experienced any waves, but that anyone near a coastline should be alert to the possibility of danger.
Authorities are monitoring the situation as the tsunami warning remains in effect.
‘You are in danger, get away from coastal waters’
Meanwhile, smartphone users received warnings urging them to move to higher ground immediately, the San Francisco Chronicle reported.
“A series of powerful waves and strong currents may impact coasts near you,” the warning said.
“You are in danger. Get away from coastal waters.”
The paper said tsunami warning sirens were activated along a stretch of the coast, including in Bonny Doon in Santa Cruz County.
The USGS, which monitors seismic activity, said the quake struck at 10.44 am local time (1844 GMT).
Media reports suggested that the quake had been felt across the region, including in the Bay Area, where some people said they had felt strong shaking and rolling waves underfoot.
The U.S. West Coast is the confluence of a number of the Earth’s tectonic plates, and tremors are not uncommon.
The area has been struck by a number of major earthquakes, including a 1994 quake that hit Northridge, in the Los Angeles area, killing dozens of people and injuring thousands more, as it wrought billions of dollars of damage to homes and infrastructure.
The San Francisco earthquake of 1906, which also caused a tsunami, is thought to have killed upwards of 3,000 people, some of whom died in fires that erupted after the powerful tremor.
