On July 10, 2026 at 20:59 UTC, a magnitude 4.3 intermediate depth earthquake struck 4 km SSW of El Pacayal, Mexico, at a depth of 222.9 km and coordinates 15.5551°, -92.0516°.

Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
