On October 14, 2020 at 23:18 UTC, a magnitude 4.5 intermediate depth earthquake struck 12 km SE of Caucete, Argentina, at a depth of 111.3 km and coordinates -31.7188°, -68.1737°.

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.
