How strong was this earthquake?

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

A magnitude 1.0 earthquake radiates roughly 0.46 kg of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 15, 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 22:21 local solar time at the epicentre, late at night.

This event was deeper than 83% of the 156,239 earthquakes recorded in the United States in our catalogue and stronger than 33% of them.

Where was the epicentre?

The epicentre was located at 37.0818, -112.8930 — 10 km northeast of Hildale. The closest other recorded event was a magnitude 1.1 earthquake 0 km southeast of here on 14 September 2026.

The nearest other settlements in our records are Colorado City (34 km south), Cane Beds (35 km south), Brian Head (42 km north) and Alton (43 km north).

Why the 17 km depth matters

At 17 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 M1.0 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

34 further earthquakes have been recorded within about 150 km of the epicentre in the 1 day since this event, the largest of them magnitude 2.6.

2 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.8 event near Caliente on 06 June 2025. This M1.0 event released about 518,800 times less energy than that event.

195 earthquakes have been recorded within 100 km of this epicentre in the past year, 22 of them in the past 30 days.

Questions about this earthquake

How strong was the earthquake near Hildale?

It measured magnitude 1.0 — a micro earthquake. A magnitude 1.0 earthquake radiates roughly 0.46 kg of TNT equivalent in seismic energy.

How deep was the earthquake near Hildale?

The focus was 17 km below the surface, which counts as shallow.

Was the Hildale earthquake felt at the surface?

At magnitude 1.0 and a focal depth of 17 km, shaking would have been concentrated near the epicentre.

When did the earthquake near Hildale happen?

14 September 2026 at 05:53 UTC.

Was there a tsunami?

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

Have there been aftershocks?

34 further earthquakes have been recorded within about 150 km of the epicentre in the 1 day since this event, the largest of them magnitude 2.6.

How often do earthquakes happen near Hildale?

2 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.8 event near Caliente on 06 June 2025. This M1.0 event released about 518,800 times less energy than that event.
