Phones across Northern California buzzed with the urgent message: “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.”
The alert came after a magnitude 7.0 earthquake struck Northern California on Thursday, December 5 at 10:44 a.m., west of Ferndale, in Humboldt County, where residents experienced several seconds of rolling motion followed by smaller aftershocks and felt as far south as San Francisco.
The tsunami warning, issued by the National Weather Service, affected over 5.3 million people, with more than 1.3 million estimated to be in the immediate vicinity. The U.S. Geological Survey issued a yellow alert predicting localized but minimal damage from the shaker.
There were no immediate reports of damage or injuries. It is one of the most powerful upheavals to hit California since a 7.1-magnitude hit Ridgecrest in 2019. Authorities have since lifted the tsunami warning.
