On August 16, 2022 at 18:17 UTC, a magnitude 4.5 intermediate depth earthquake struck 44 km S of Pocito, Argentina, at a depth of 131.1 km and coordinates -32.0794°, -68.5550°. This earthquake was detected by 49 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.
