Tsunami Warning for California Today

On April 24, 2026, a powerful 7.0‑magnitude earthquake struck the Pacific Northwest, approximately 60 miles offshore of Ferndale, California. The U.S. National Weather Service (NWS) promptly issued a Tsunami Warning for coastal regions of California, alerting residents and visitors to take immediate precautions.

The seismic event was recorded by the Pacific Northwest Seismic Network. Its epicenter was located in the deep ocean, well below the continental shelf. While the earthquake caused minor shaking along the California coast, the most significant concern is the potential for a tsunami generated by the seafloor displacement.
