M2.5 Earthquake near Akiachak, United States — 02 April 2026, 08:50 UTC

Minor earthquakes in this range are felt by people close to the epicentre as a brief jolt or rattle, but they very rarely cause any damage.

A magnitude 2.5 earthquake radiates roughly 85 kg of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 96, which is below the USGS threshold of more than 600 for its significant-earthquake list. The ranking combines magnitude with available Did You Feel It responses and PAGER alert level; it is not a direct measurement of damage.

That is about 22:02 local solar time at the epicentre, late at night.

This event was deeper than 100% of the 161,377 earthquakes recorded in the United States in our catalogue and stronger than 92% of them.

The epicentre was located at 61.1150, -161.8120 — 30 km northwest of Akiachak. The closest other recorded event was a magnitude 3.4 earthquake 81 km east-northeast of here on 23 March 2026.

The nearest other settlements in our records are Lower Kalskag (83 km east-northeast), Pilot Station (106 km north-northwest), Quinhagak (183 km south) and Togiak (198 km south-southeast).

At 545 km this was a deep-focus earthquake, occurring well inside the subducting slab rather than in the crust. Deep events are rarely damaging even at large magnitudes, though they can be felt over very long distances.

This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size may be noticed locally, especially close to the epicentre. Its deep focus normally weakens surface shaking while spreading perceptible motion over a broad area.

The USGS record does not carry a link to NOAA tsunami information. That field is not an all-clear and does not state whether a tsunami occurred. In this case, a damaging tsunami would be less likely because at M2.5 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 545 km focal depth is too great to deform the sea floor significantly; it occurred inland rather than beneath the sea floor. For an active coastal alert, use tsunami.gov or your local warning authority.

1 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 2.4.

0 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 3.4 event near Lower Kalskag on 23 March 2026. This M2.5 event released about 22 times less energy than that event.

1 earthquakes have been recorded within 100 km of this epicentre in the past year, 1 of them in the past 30 days.
