M4.5 Earthquake near Puerto Natales, Chile — 26 March 2025

Light earthquakes are widely felt near the epicentre and can rattle windows, dishes and hanging objects. Damage is uncommon and usually limited to cracked plaster or fallen loose items.

A magnitude 4.5 earthquake radiates roughly 85 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 312, 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 02:29 local solar time at the epicentre, in the early hours of the morning.

This event was shallower than 87% of the 727 earthquakes recorded in Chile in our catalogue and stronger than 60% of them.

The epicentre was located at -52.4184, -71.6766 — 95 km southeast of Puerto Natales. The closest other recorded event was a magnitude 4.2 earthquake 11 km west-southwest of here on 31 October 2025.

The nearest other settlement in our records is 28 de Noviembre (106 km north).

At 15 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 is often felt across the surrounding area. 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 M4.5 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.

5 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 5.2 event near 28 de Noviembre on 13 May 2025. This M4.5 event released about 11 times less energy than that event.

1 earthquakes have been recorded within 100 km of this epicentre in the past year, 0 of them in the past 30 days.
