On January 19, 2024 at 09:40 UTC, a magnitude 5.1 intermediate depth earthquake struck 144 km NNW of Antofagasta de la Sierra, Argentina, at a depth of 114.8 km and coordinates -24.7895°, -67.7423°. This earthquake was detected by 116 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 400, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
