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 2.2 earthquake radiates roughly 30 kg of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 74, 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 13:58 local solar time at the epicentre, around midday.

This event was deeper than 99% of the 153,855 earthquakes recorded in the United States in our catalogue and stronger than 87% of them.

Where was the epicentre?

The epicentre was located at 59.7200, -153.3140 — 45 km east of Pedro Bay. The closest other recorded event was a magnitude 2.3 earthquake 11 km north of here on 03 September 2026.

The nearest other settlements in our records are Aleneva (197 km south) and Alaska Peninsula National Wildlife Refuge (228 km south-southwest).

Why the 132 km depth matters

At 132 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, events this small are usually detected by instruments rather than people. 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 M2.2 it falls below the magnitude 6.5 threshold that generally applies before a submarine earthquake displaces enough water to generate a damaging tsunami; its 132 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.

Aftershocks and local seismic history

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

28 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.6 event near Aleneva on 25 April 2025. This M2.2 event released about 3,981 times less energy than that event.

3171 earthquakes have been recorded within 100 km of this epicentre in the past year, 235 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Pedro Bay?

It measured magnitude 2.2 — a minor earthquake. A magnitude 2.2 earthquake radiates roughly 30 kg of TNT equivalent in seismic energy.

How deep was the earthquake near Pedro Bay?

The focus was 132 km below the surface, which counts as intermediate.

Was the Pedro Bay earthquake felt at the surface?

At magnitude 2.2 and a focal depth of 132 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Pedro Bay happen?

06 September 2026 at 00:11 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 since this event was recorded.

How often do earthquakes happen near Pedro Bay?

28 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.6 event near Aleneva on 25 April 2025. This M2.2 event released about 3,981 times less energy than that event.
