On October 23, 2020 at 18:21 UTC, a magnitude 4.2 intermediate depth earthquake struck 11 km ESE of Nueva Concepción, Guatemala, at a depth of 73.4 km and coordinates 14.1517°, -91.2007°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
