How strong was this earthquake?
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 2.1 earthquake radiates roughly 21 kg of TNT equivalent in seismic energy.
The USGS assigns this earthquake a significance score of 68, 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.

When it happened locally
That is about 19:21 local solar time at the epicentre, in the evening.
This event was deeper than 76% of the 161,634 earthquakes recorded in the United States in our catalogue and stronger than 86% of them.
Where was the epicentre?
The epicentre was located at 54.5900, -163.0520 — 37 km southeast of False Pass. The closest other recorded event was a magnitude 0.8 earthquake 29 km west of here on 27 August 2026.
The nearest other settlements in our records are Cold Bay (50 km north-northeast), False Pass (202 km south) and Akutan (229 km south-southwest).
Why the 12 km depth matters
At 12 km this was a shallow earthquake. Shallow events release their energy close to the surface, so for a given magnitude they produce noticeably stronger shaking — and more damage — than deeper ones. Roughly three quarters of all earthquakes worldwide occur at shallow depths.
This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, events this small are usually detected by instruments rather than people. Its shallow focus makes stronger surface shaking more likely than for a deeper event of the same magnitude.

What does the tsunami information flag mean?
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 M2.1 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; it occurred inland rather than beneath the sea floor. For an active coastal alert, use tsunami.gov or your local warning authority.

Aftershocks and local seismic history
No further earthquakes have been recorded within about 150 km of the epicentre in the 1 day since this event.
45 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.4 event near False Pass on 14 July 2026. This M2.1 event released about 89,125 times less energy than that event.
185 earthquakes have been recorded within 100 km of this epicentre in the past year, 7 of them in the past 30 days.
