On December 4, 2022 at 21:04 UTC, a magnitude 5.0 intermediate depth earthquake struck 48 km SW of Andalgalá, Argentina, at a depth of 168.4 km and coordinates -27.9289°, -66.6214°. This earthquake was detected by 102 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 385, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
