On August 8, 2026 at 12:28 UTC, a magnitude 4.2 intermediate depth earthquake struck 8 km SSE of Puerto Madero, Mexico, at a depth of 75.6 km and coordinates 14.6490°, -92.4058°.
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.
