On June 26, 2020 at 13:45 UTC, a magnitude 4.7 intermediate depth earthquake struck 33 km NW of San Carlos, Argentina, at a depth of 182.7 km and coordinates -30.9507°, -65.3416°.

Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 km — a useful intuition for the size of the slip patch on the fault.
