On March 2, 2025 at 22:23 UTC, a magnitude 4.6 intermediate depth earthquake struck 41 km S of La Tirana, Chile, at a depth of 89.4 km and coordinates -20.7010°, -69.5885°. This earthquake was detected by 46 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 327, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
