What Happened

A minor earthquake with a magnitude of 3.1 ml was recorded southwest of Karluk, Alaska. The seismic event occurred at 15:33 UTC on March 22, 2026 (1771688038469). According to the U.S. Geological Survey (USGS), the earthquake originated at a depth of 57 kilometers.

Location Details

The epicenter was located at coordinates 57.305°N, 154.988°W, approximately 43 kilometers (26.7 miles) southwest of Karluk, Alaska. The depth of 57 kilometers classifies this as an intermediate-depth earthquake. Intermediate earthquakes, occurring between 20 and 70 km below the surface, typically result in less intense surface shaking than shallow events of the same magnitude.

Impact Assessment

At this time, there are no felt reports associated with this event. There is no tsunami advisory, watch, or warning in effect. Given the magnitude and location, no damage to structures is expected, and the USGS has not issued a specific alert level color for this routine seismic activity.

What You Should Know

Earthquakes with magnitudes between 2.5 and 3.9 are classified as minor. While they are frequently recorded in seismically active regions like Alaska, they are rarely strong enough to cause damage. Residents are reminded that aftershocks are a common occurrence following seismic events, though they are typically smaller than the initial quake.
