On January 12, 2022 at 19:57 UTC, a magnitude 4.1 shallow crustal earthquake struck 40 km S of El Carrizal, Mexico, at a depth of 35.0 km and coordinates 15.7074°, -95.3312°.

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.
