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 2.5 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.

When it happened locally

That is about 06:03 local solar time at the epicentre, around dawn.

This event was deeper than 96% of the 161,089 earthquakes recorded in the United States in our catalogue and stronger than 92% of them.

Where was the epicentre?

The epicentre was located at 53.7460, -164.6590 — 85 km east-southeast of Akutan. The closest other recorded event was a magnitude 2.4 earthquake 21 km southwest of here on 04 September 2026.

The nearest other settlement in our records is Akutan (208 km southeast).

Why the 76 km depth matters

At 76 km this was an intermediate-depth earthquake. Energy from events at this depth spreads out before it reaches the surface, which usually means weaker shaking near the epicentre than a shallow quake of the same magnitude, but shaking felt across a wider area.

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 intermediate depth normally reduces peak shaking near the epicentre compared with a shallow 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 M2.5 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 3 hours since this event.

37 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 Akutan on 25 April 2026. This M2.5 event released about 22,387 times less energy than that event.

275 earthquakes have been recorded within 100 km of this epicentre in the past year, 5 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Akutan?

It measured magnitude 2.5 — a minor earthquake. A magnitude 2.5 earthquake radiates roughly 85 kg of TNT equivalent in seismic energy.

How deep was the earthquake near Akutan?

The focus was 76 km below the surface, which counts as intermediate.

Was the Akutan earthquake felt at the surface?

At magnitude 2.5 and a focal depth of 76 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Akutan happen?

07 October 2026 at 17:02 UTC.

Was there a tsunami?

No. The USGS record carries no tsunami-information link for this event.

Have there been aftershocks?

No further earthquakes have been recorded within about 150 km of the epicentre in the 3 hours since this event.

How often do earthquakes happen near Akutan?

37 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 Akutan on 25 April 2026. This M2.5 event released about 22,387 times less energy than that event.
