A powerful earthquake struck on Thursday off the coast of California, sparking a tsunami warning, US seismologists said.
The 7.0-magnitude quake was recorded at a depth of just 10 kilometers (six miles), almost 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 300km 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.
