On February 16, 2025 at 23:25 UTC, a magnitude 4.3 shallow crustal earthquake struck 17 km S of Coquimbo, Chile, at a depth of 67.5 km and coordinates -30.1096°, -71.3255°.
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.
