On November 15, 2021 at 21:03 UTC, a magnitude 4.6 intermediate depth earthquake struck 98 km W of San Antonio de los Cobres, Argentina, at a depth of 184.8 km and coordinates -24.2075°, -67.2880°.

Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
