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 2.8 earthquake radiates roughly 239 kg of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 121, 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 13:42 local solar time at the epicentre, around midday.

This event was shallower than 58% of the 154,009 earthquakes recorded in the United States in our catalogue and stronger than 96% of them.

Where was the epicentre?

The epicentre was located at 68.6390, -148.6550 — 138 km east-northeast of Anaktuvuk Pass. The closest other recorded event was a magnitude 2.3 earthquake 21 km southeast of here on 09 August 2026.

The nearest other settlements in our records are Anaktuvuk Pass (22 km south), Arctic Village (77 km south-southeast), Prudhoe Bay (95 km northeast) and Bettles Field (97 km south).

Why the 5 km depth matters

At 5 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, an event this size may be noticed locally, especially close to the epicentre. 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 M2.8 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 since this event was recorded.

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 3.9 event near Prudhoe Bay on 05 September 2026. This M2.8 event released about 45 times less energy than that event.

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