A minor earthquake with a magnitude of 3.0 (ml) occurred on March 5, 2026, at 06:35:00 UTC. The seismic event was centered approximately 230 km southeast of Chiniak, Alaska. The earthquake occurred at a shallow depth of 5 kilometers.

Location Details

The earthquake’s epicenter was located at coordinates 56.344°N and 149.281°W. This location is in the Gulf of Alaska, southeast of the Kodiak Island archipelago. The depth of 5 kilometers is considered very shallow; earthquakes occurring at depths less than 20 kilometers are categorized as shallow and are more likely to be felt if they occur near populated areas.

Impact Assessment

According to the USGS, there was no tsunami advisory, watch, or warning issued in connection with this event. As of the latest report, there have been no citizen-submitted felt reports recorded for this earthquake. Given the magnitude and the remote offshore location, no damage or injuries are expected from this event.

What You Should Know

Earthquakes with magnitudes between 2.5 and 3.9 are classified as minor. While they are often recorded by seismographs, they are rarely felt by people unless they are very close to the epicenter, and they typically do not cause structural damage. Routine seismic activity is common in the coastal regions of Alaska.
