The United States Geological Survey has reported a 7.0 magnitude earthquake off the Northern California coast.
The epicenter of the quake is about 40 miles northwest of Ferndale.
"Most of the slip was lateral, reducing the risk of a severe #tsunami, but some was thrust (up/down), which makes waves," meteorologist Matthew Cappucci wrote on X.
