On December 22, 2023 at 19:02 UTC, a magnitude 4.2 intermediate depth earthquake struck 58 km WSW of Abra Pampa, Argentina, at a depth of 245.2 km and coordinates -22.8368°, -66.2550°.
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.
