On June 13, 2023 at 19:51 UTC, a magnitude 4.2 intermediate depth earthquake struck 21 km NNE of Calama, Chile, at a depth of 128.1 km and coordinates -22.2827°, -68.8215°.
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.
