On January 31, 2025 at 22:19 UTC, a magnitude 4.4 intermediate depth earthquake struck 117 km NNW of San José de Jáchal, Argentina, at a depth of 113.8 km and coordinates -29.2840°, -69.2716°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
