On November 5, 2022 at 12:12 UTC, a magnitude 5.1 shallow crustal earthquake struck 34 km SSW of San Mart?n, Argentina, at a depth of 36.3 km and coordinates -33.3848°, -68.5697°. This earthquake was detected by 152 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 421, 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.
