How strong was this earthquake?

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

A magnitude 1.9 earthquake radiates roughly 11 kg of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 56, 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 03:56 local solar time at the epicentre, in the early hours of the morning.

This event was deeper than 81% of the 167,993 earthquakes recorded in the United States in our catalogue and stronger than 80% of them.

Where was the epicentre?

The epicentre was located at 62.2650, -149.9030 — 11 km north-northwest of Susitna North. The closest other recorded event was a magnitude 1.7 earthquake 12 km west-southwest of here on 07 November 2026.

The nearest other settlements in our records are Beluga (142 km south-southwest), Anchorage (166 km south-southeast) and Bear Creek (222 km south).

Why the 15 km depth matters

At 15 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 M1.9 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

1 further earthquakes have been recorded within about 150 km of the epicentre in the 2 hours since this event, the largest of them magnitude 2.1.

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 6.0 event near Susitna on 27 November 2025. This M1.9 event released about 1.4 million times less energy than that event.

1869 earthquakes have been recorded within 100 km of this epicentre in the past year, 143 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Susitna North?

It measured magnitude 1.9 — a micro earthquake. A magnitude 1.9 earthquake radiates roughly 11 kg of TNT equivalent in seismic energy.

How deep was the earthquake near Susitna North?

The focus was 15 km below the surface, which counts as shallow.

Was the Susitna North earthquake felt at the surface?

At magnitude 1.9 and a focal depth of 15 km, shaking would have been concentrated near the epicentre.

When did the earthquake near Susitna North happen?

10 November 2026 at 13:55 UTC.

Was there a tsunami?

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

Have there been aftershocks?

1 further earthquakes have been recorded within about 150 km of the epicentre in the 2 hours since this event, the largest of them magnitude 2.1.

How often do earthquakes happen near Susitna North?

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 6.0 event near Susitna on 27 November 2025. This M1.9 event released about 1.4 million times less energy than that event.
