On June 9, 2021 at 22:17 UTC, a magnitude 4.1 shallow crustal earthquake struck 55 km SW of Los Mogotes, Mexico, at a depth of 14.8 km and coordinates 16.5474°, -100.3984°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
