On August 7, 2023 at 22:19 UTC, a magnitude 4.1 shallow crustal earthquake struck 72 km SSW of Cabeza de Toro, Mexico, at a depth of 54.9 km and coordinates 15.3871°, -94.1460°.
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.
