On January 30, 2022 at 02:44 UTC, a magnitude 4.8 shallow crustal earthquake struck 45 km ESE of Humahuaca, Argentina, at a depth of 10.0 km and coordinates -23.3030°, -64.9234°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
