On August 30, 2023 at 20:26 UTC, a magnitude 4.4 shallow crustal earthquake struck 15 km NNE of Petatlán, Mexico, at a depth of 42.7 km and coordinates 17.6579°, -101.2008°.
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
