On January 5, 2023 at 19:08 UTC, a magnitude 4.2 shallow crustal earthquake struck 10 km NNW of Hacienda La Calera, Chile, at a depth of 58.0 km and coordinates -32.7048°, -71.2694°.
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.
