On June 25, 2024 at 16:21 UTC, a magnitude 4.2 intermediate depth earthquake struck 45 km S of Calama, Chile, at a depth of 95.3 km and coordinates -22.8716°, -68.9083°.
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.
