How strong was this earthquake?

Micro earthquakes are almost never felt at the surface and are recorded only by seismographs.

A magnitude 1.4 earthquake radiates roughly 1.9 kg of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 30, 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 16:36 local solar time at the epicentre, during the afternoon.

This event was deeper than 97% of the 167,514 earthquakes recorded in the United States in our catalogue and stronger than 56% of them.

Where was the epicentre?

The epicentre was located at 57.9240, -154.8640 — 46 km north-northwest of Karluk. The closest other recorded event was a magnitude 3.0 earthquake 6 km northwest of here on 06 November 2026.

The nearest other settlements in our records are Alaska Peninsula National Wildlife Refuge (96 km west-southwest) and Akhiok (228 km south-southwest).

Why the 88 km depth matters

At 88 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 M1.4 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.

25 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.6 event near Akhiok on 22 December 2024. This M1.4 event released about 2.0 million times less energy than that event.

2586 earthquakes have been recorded within 100 km of this epicentre in the past year, 202 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Karluk?

It measured magnitude 1.4 — a micro earthquake. A magnitude 1.4 earthquake radiates roughly 1.9 kg of TNT equivalent in seismic energy.

How deep was the earthquake near Karluk?

The focus was 88 km below the surface, which counts as intermediate.

Was the Karluk earthquake felt at the surface?

At magnitude 1.4 and a focal depth of 88 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Karluk happen?

08 November 2026 at 02:55 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 Karluk?

25 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.6 event near Akhiok on 22 December 2024. This M1.4 event released about 2.0 million times less energy than that event.
