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 3.4 earthquake radiates roughly 1.9 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 178, 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 12:25 local solar time at the epicentre, around midday.

This event was shallower than 99% of the 1,065 earthquakes recorded in Mexico in our catalogue and stronger than 67% of them.

Where was the epicentre?

The epicentre was located at 31.5808, -115.5990 — 83 km south-southwest of Alberto Oviedo Mota, B.C.. The closest other recorded event was a magnitude 1.3 earthquake 115 km north of here on 02 October 2026.

The nearest other settlement in our records is Aguanga (239 km north-northwest).

Why the -0 km depth matters

At -0 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, an event this size may be noticed locally, especially close to the epicentre. 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 M3.4 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

34 further earthquakes have been recorded within about 150 km of the epicentre in the seven days after this event, the largest of them magnitude 2.2.

20 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 San Diego Country Estates on 14 April 2025. This M3.4 event released about 7,839 times less energy than that event.

228 earthquakes have been recorded within 100 km of this epicentre in the past year, 16 of them in the past 30 days.
