M2.2 Earthquake near Pultneyville, United States — 22 October 2025, 23:19 UTC

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 78, 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.

That is about 18:10 local solar time at the epicentre, in the evening.

This event was deeper than 61% of the 154,251 earthquakes recorded in the United States in our catalogue and stronger than 87% of them.

The epicentre was located at 43.3957, -77.1749 — 12 km north of Pultneyville. The closest other recorded event was a magnitude 2.8 earthquake 67 km east-northeast of here on 21 March 2026.

The nearest other settlements in our records are Henderson (67 km east-northeast), Honeoye (69 km south-southwest), Adams Center (105 km east-northeast) and Evans Mills (137 km northeast).

At 8 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.

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; it occurred inland rather than beneath the sea floor. For an active coastal alert, use tsunami.gov or your local warning authority.

No further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event.

1 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 4.1 event near Amigo Beach on 28 January 2026. This M2.2 event released about 708 times less energy than that event.

No other earthquakes have been recorded within 100 km of this epicentre in the past year, which makes this a genuinely isolated event.
