How strong was this earthquake?

Strong earthquakes can cause significant damage in populated areas within roughly 100 km of the epicentre, particularly to older masonry buildings. Landslides and liquefaction become a real risk in susceptible ground.

A magnitude 6.4 earthquake radiates roughly 60,036 tons of TNT equivalent in seismic energy.

The USGS assigns this earthquake a significance score of 644, which meets 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 12:33 local solar time at the epicentre, around midday.

This event was shallower than 52% of the 728 earthquakes recorded in Chile in our catalogue and stronger than 100% of them.

Where was the epicentre?

The epicentre was located at -26.6448, -70.4891 — 52 km west-southwest of Diego de Almagro. The closest other recorded event was a magnitude 4.5 earthquake 36 km east-northeast of here on 02 January 2026.

The nearest other settlements in our records are Taltal (88 km northwest), Copiapó (106 km south-southeast), Huasco (173 km south-southwest) and Vallenar (236 km south-southwest).

Why the 77 km depth matters

At 77 km this was an intermediate-depth earthquake. Energy from events at this depth spreads out before it reaches the surface, which usually means weaker shaking near the epicentre than a shallow quake of the same magnitude, but shaking felt across a wider area.

This catalogue does not ingest eyewitness responses, so it cannot confirm where this earthquake was felt. Based on magnitude alone, an event this size can produce strong, widely felt shaking. Its intermediate depth normally reduces peak shaking near the epicentre compared with a shallow event of the same magnitude.

What does the tsunami information flag mean?

The USGS event record links to NOAA tsunami information because this was a large event in an oceanic region. That link flag does not mean a tsunami occurred or that a warning is active. Check tsunami.gov and instructions from your local authority for the current status of your coastline.

Aftershocks and local seismic history

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

60 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.5 event near Diego de Almagro on 06 June 2025. This M6.4 event released about 1.4 times less energy than that event.

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

Questions about this earthquake

How strong was the earthquake near Diego de Almagro?

It measured magnitude 6.4 — a strong earthquake. A magnitude 6.4 earthquake radiates roughly 60,036 tons of TNT equivalent in seismic energy.

How deep was the earthquake near Diego de Almagro?

The focus was 77 km below the surface, which counts as intermediate.

Was the Diego de Almagro earthquake felt at the surface?

At magnitude 6.4 and a focal depth of 77 km, the depth spreads the energy out, so shaking is weaker overhead but reaches further.

When did the earthquake near Diego de Almagro happen?

06 June 2025 at 17:15 UTC.

Was there a tsunami?

The USGS record carries a link to NOAA tsunami information for this event. That is not a warning: check your regional tsunami warning centre for any live alert.

Have there been aftershocks?

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

How often do earthquakes happen near Diego de Almagro?

60 earthquakes of magnitude 4 or above have been logged within roughly 200 km of this epicentre in our catalogue. The strongest was a magnitude 6.5 event near Diego de Almagro on 06 June 2025. This M6.4 event released about 1.4 times less energy than that event.
