On December 4, 2024 at 17:46 UTC, a magnitude 4.2 shallow crustal earthquake struck 64 km SW of Coquimbo, Chile, at a depth of 29.0 km and coordinates -30.2890°, -71.8921°.
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.
