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 2.2 earthquake radiates roughly 29 kg of TNT equivalent in seismic energy.
The USGS assigns this earthquake a significance score of 74, 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 18:46 local solar time at the epicentre, in the evening.
This event was shallower than 63% of the 3,712 earthquakes recorded in Puerto Rico in our catalogue and stronger than 26% of them.
Where was the epicentre?
The epicentre was located at 18.0098, -66.7607 — 1 km southeast of Magas Arriba. The closest other recorded event was a magnitude 2.2 earthquake 2 km west-northwest of here on 02 September 2026.
The nearest other settlements in our records are Adjuntas (13 km north-northeast), Boquerón (38 km west), Bajadero (40 km north) and Arecibo (49 km north).
Why the 13 km depth matters
At 13 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 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.

Aftershocks and local seismic history
85 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 5.0.
98 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.9 event near Punta Cana on 25 February 2025. This M2.2 event released about 367,282 times less energy than that event.
1501 earthquakes have been recorded within 100 km of this epicentre in the past year, 179 of them in the past 30 days.
