On June 1, 2021 at 02:48 UTC, a magnitude 4.8 shallow crustal earthquake struck 23 km WNW of San Agustín de Valle Fértil, Argentina, at a depth of 44.8 km and coordinates -30.5734°, -67.7086°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 km — a useful intuition for the size of the slip patch on the fault.
