On March 21, 2022 at 21:01 UTC, a magnitude 4.2 intermediate depth earthquake struck 8 km E of Chamulapita, Mexico, at a depth of 97.1 km and coordinates 15.0617°, -92.2951°.

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.
