On September 21, 2023 at 18:41 UTC, a magnitude 4.2 intermediate depth earthquake struck 4 km SE of Abasolo del Valle, Mexico, at a depth of 107.6 km and coordinates 17.7540°, -95.5183°.

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.
