On October 9, 2026 at 10:22 UTC, a magnitude 5.1 intermediate depth earthquake struck 72 km SSW of Colchane, Chile, at a depth of 123.8 km and coordinates -19.9128°, -68.7905°. This earthquake was detected by 98 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 402, 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.
