On June 6, 2021 at 20:05 UTC, a magnitude 4.5 intermediate depth earthquake struck 35 km SE of Calingasta, Argentina, at a depth of 108.7 km and coordinates -31.5493°, -69.1505°.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
