A powerful 7.5 magnitude earthquake struck off the coast of Alaska on Wednesday afternoon, triggering tsunami warnings for thousands of residents in coastal communities. The quake, detected by the U.S. Geological Survey (USGS) at 4:30 p.m. ET, originated in the Pacific Ocean near the Shumagin Islands, approximately 60 miles southeast of Sand Point.

Tsunami warnings have been issued for southwestern Alaska, including Kodiak Island and the Aleutian Islands.

Immediate Threats and Evacuations

The National Tsunami Warning Center issued alerts for coastal regions stretching from Kennedy Entrance near Homer to Unimak Pass near Unalaska. Over 17,000 residents in remote towns and islands were urged to move to higher ground as sirens blared. While no tsunami has been confirmed yet, officials warned of potential "dangerous coastal flooding and strong currents" lasting hours.

Second Earthquake Hits Halibut Cove

A follow-up 4.0 magnitude tremor shook Halibut Cove—a community of 200 people—roughly an hour later. Though smaller, it added to anxieties in the region.

A second quake struck near Halibut Cove, amplifying concerns.

Ongoing Monitoring

Authorities are closely tracking ocean activity and conducting safety assessments. Residents are advised to avoid shorelines until the all-clear is given.
