Strong M6.9 earthquake strikes Antofagasta region, Chile (Updated)

An earthquake with a magnitude of M6.9 was recorded at 21:52 UTC on May 25, 2026, approximately 29 km (18 miles) east-northeast of Calama, Chile. The event occurred at a depth of 109.0 km (67.7 miles).

The coordinates for the epicenter are 22.4°S, 68.6°W, placing the quake inland within the Antofagasta region of northern Chile. Calama is a regional hub in this area, surrounded by the arid landscapes of the Atacama Desert. The region is home to several mining towns and hubs of economic activity.

Given its inland location, the affected zone may include highways and arterial roads connecting mining sites, as well as potential proximity to power transmission infrastructure and mining operations that are characteristic of the region. Major airports and ports are located further away toward the Pacific coast but are a critical part of the regional economy.

There is no tsunami threat associated with this earthquake, based on its location and available data.

A total of 46 felt reports were submitted for this event. The significance index is 755 (on a scale that runs through 1 000), based on magnitude, felt reports, and estimated impact.

Northern Chile lies within the seismically active boundary between the Nazca and South American tectonic plates. This region frequently experiences significant tectonic activity due to subduction-related processes along the Peru-Chile trench.
