On November 13, 2022 at 22:05 UTC, a magnitude 4.2 shallow crustal earthquake struck 86 km WNW of La Ligua, Chile, at a depth of 21.7 km and coordinates -32.1111°, -72.0510°.
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.
