On October 23, 2020 at 16:29 UTC, a magnitude 5.0 intermediate depth earthquake struck 21 km NW of Londres, Argentina, at a depth of 123.4 km and coordinates -27.5866°, -67.2969°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
