Earthquake Chile of medium intensity reached VI Mercalli in Antofagasta on May 25
The earthquake chile on May 25 2026 registered as a medium-intensity event that drew official attention across northern portions of the country. Reports placed the main shock at 17:53 local time with a maximum perceived intensity of VI on the Mercalli scale in several Antofagasta localities.
Event Summary
A medium-intensity earthquake was felt across northern Chile on May 25 2026 reaching maximum intensity VI Mercalli in Antofagasta Tocopilla Mejillones and Sierra Gorda. The event occurred at 17:53 hours and was described in official bulletins as a sismo de mediana intensidad. [3]
Technical Parameters
Instrumented data recorded two distinct events that contributed to the overall sequence. A magnitude 4.1 earthquake occurred 15 km ESE of Calama at 111.2 km depth. [4] Separately a magnitude 3.6 earthquake occurred 9 km SW of Cavancha at 82.4 km depth. [1] These parameters come directly from seismic network recordings and provide the only quantitative details available for the main shocks.

Geographic Extent
The quake was reported between the regions of Arica y Parinacota and Atacama. [3] Maximum perceived intensity reached VI Mercalli in the listed Antofagasta communities while lower intensities were noted farther north and south within the stated regional corridor.
Follow-up Activity
Additional temblor reports were issued for Chile on May 27 and May 28 2026. [2] [5] These daily updates catalogued further minor events and confirmed that seismic monitoring continued without interruption after the initial May 25 activity.
Regional Monitoring Context
Seismic networks maintained continuous coverage from Arica y Parinacota through Atacama during the period. The reported depths of 82.4 km and 111.2 km placed both main events well below the surface, consistent with typical subduction-zone patterns observed in the same corridor.
Instrumented Data Review
Cross-referencing of the magnitude 4.1 and magnitude 3.6 readings supplied the only verified epicentral coordinates released for the sequence. No surface damage assessments beyond intensity descriptions appear in the source material.

What to watch next: Daily temblor summaries for Chile are scheduled to continue on the pattern established for May 27 and May 28 2026.
