On July 24, 2024 at 23:12 UTC, a magnitude 4.3 intermediate depth earthquake struck 53 km NE of Calama, Chile, at a depth of 130.4 km and coordinates -22.0677°, -68.6186°.
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.
