On May 27, 2026 at 05:23 UTC, a magnitude 5.1 intermediate depth earthquake struck 27 km NE of Calama, Chile, at a depth of 102.7 km and coordinates -22.2673°, -68.7550°. This earthquake was detected by 100 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 401, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Chile, a region characterized by the Peru-Chile Trench, where the Nazca Plate subducts beneath South America at 65-80 mm per year. The nearest mapped fault system is the Peru-Chile Trench. View all earthquakes in Chile.
