On September 3, 2022 at 20:27 UTC, a magnitude 4.6 shallow crustal earthquake struck 20 km SSW of Pocito, Argentina, at a depth of 23.7 km and coordinates -31.8482°, -68.6914°. This earthquake was detected by 49 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — a useful intuition for the size of the slip patch on the fault.
