On May 13, 2025 at 00:48 UTC, a magnitude 5.2 shallow crustal earthquake struck 35 km NE of 28 de Noviembre, Argentina, at a depth of 10.0 km and coordinates -51.3717°, -71.8409°. This earthquake was detected by 72 seismic stations with good location accuracy and was assigned a USGS significance rating of 421, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 5.2 releases seismic energy equivalent to roughly 951 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.3 km — a useful intuition for the size of the slip patch on the fault.
