On January 11, 2024 at 17:28 UTC, a magnitude 4.3 shallow crustal earthquake struck 35 km WSW of Santa Cruz, Chile, at a depth of 53.1 km and coordinates -34.7776°, -71.7116°.
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.
