On January 8, 2023 at 19:28 UTC, a magnitude 4.3 shallow crustal earthquake struck 3 km NNE of Villa Alemana, Chile, at a depth of 54.5 km and coordinates -33.0128°, -71.3559°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
