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 3.6 earthquake radiates roughly 3.8 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 201, 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 08:54 local solar time at the epicentre, during the morning.

This event was shallower than 62% of the 751 earthquakes recorded in Chile in our catalogue and stronger than 2% of them.

Where was the epicentre?

The epicentre was located at -20.2772, -70.0833 — 2 km east-southeast of Alto Hospicio. The closest other recorded event was a magnitude 3.2 earthquake 13 km south of here on 28 July 2026.

The nearest other settlements in our records are Cavancha (14 km west), Barrio Industrial (28 km north-northwest), Huara (30 km northeast) and Cuya (93 km north).

Why the 49 km depth matters

At 49 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 M3.6 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 seven days after this event, the largest of them magnitude 5.0.

285 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.1 event near María Elena on 02 January 2025. This M3.6 event released about 5,623 times less energy than that event.

17 earthquakes have been recorded within 100 km of this epicentre in the past year, 6 of them in the past 30 days.
