On May 29, 2020 at 10:10 UTC, a magnitude 4.8 intermediate depth earthquake struck 51 km W of El Aguilar, Argentina, at a depth of 213.8 km and coordinates -23.2182°, -66.1858°.

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.
