On May 22, 2022 at 19:23 UTC, a magnitude 4.5 shallow crustal earthquake struck 50 km NE of Caucete, Argentina, at a depth of 57.9 km and coordinates -31.2971°, -67.9492°. This earthquake was detected by 32 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 m — a useful intuition for the size of the slip patch on the fault.
