A robust 7.0 magnitude earthquake struck offshore from Northern California and Oregon on Thursday, triggering a temporary tsunami warning that was quickly lifted. The seismic event occurred at 9:12 a.m. local time, approximately 80 miles west of Crescent City, California, causing initial concern but resulting in no reported damage or injuries.
The National Tsunami Warning Center swiftly issued an alert following the quake, activating emergency sirens in coastal regions and advising residents to avoid shorelines. Within just over an hour, the warning was canceled after scientists determined the underwater earthquake’s characteristics made significant wave generation unlikely.
Seismologists are closely monitoring potential aftershocks. Dr. Lucy McBride from the U.S. Geological Survey noted that earthquakes of this magnitude typically generate smaller subsequent tremors, advising communities to remain cautious but not alarmed.
The earthquake occurred in the geologically active Cascadia Subduction Zone, an area known for producing powerful seismic events. The last major regional earthquake was the 2014 Napa earthquake, which caused substantial damage.
Local and state officials used the event to emphasize earthquake and tsunami preparedness. California Governor Gavin Newsom highlighted the importance of having emergency plans and supplies ready, urging residents to review evacuation routes.
Residents from coastal communities reported feeling a strong, rolling motion lasting about 20 seconds. Mike Thompson, a local fisherman, described the experience as intense but not unprecedented. Social media platforms became venues for sharing earthquake experiences, with many expressing relief that no tsunami emerged.
Preliminary infrastructure inspections revealed no significant structural damage. Power outages were minimal, and essential services were quickly restored.
Experts continue to recommend that residents in earthquake-prone regions follow safety protocols like “Drop, Cover, and Hold On” and stay informed through official channels such as the USGS Earthquake Hazards Program website.
