A minor earthquake with a magnitude of 3.1 ml occurred on Tuesday, February 17, 2026, at 13:32 UTC (4:32 AM local time). The seismic event was centered approximately 94 kilometers (58 miles) southwest of Tanana, Alaska.

Location Details

The earthquake’s epicenter was recorded at coordinates 64.579°N and 153.521°W. The event occurred at a very shallow depth of 2.4 kilometers. In seismology, events occurring at depths of less than 20 kilometers are considered shallow; these are often more noticeable to those nearby than deeper seismic activity.

Impact Assessment

What You Should Know

Earthquakes with magnitudes between 2.5 and 3.9 are classified as minor. While these events are frequently recorded and sometimes felt by residents, they rarely cause damage to structures. Residents in seismic zones are reminded that aftershocks are possible following any earthquake, though they are generally smaller than the initial event.
