On September 18, 2026 at 16:52 UTC, a magnitude 5.2 intermediate depth earthquake struck 28 km NE of Villa Presidente Frei, Chile, at a depth of 100.0 km and coordinates -33.3109°, -70.3344°. This earthquake was detected by 82 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 424, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 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.
