On September 21, 2026 at 11:02 UTC, a magnitude 4.2 intermediate depth earthquake struck 15 km SW of El Ramal (Porvenir), Mexico, at a depth of 142.8 km and coordinates 15.7541°, -93.0352°.

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.
