On October 5, 2025 at 22:42 UTC, a magnitude 4.2 shallow crustal earthquake struck 36 km ENE of Villa Presidente Frei, Chile, at a depth of 8.8 km and coordinates -33.3548°, -70.2052°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
