On November 11, 2026 at 11:01 UTC, a magnitude 4.0 shallow crustal earthquake struck 10 km NE of San Agustín Chayuco, Mexico, at a depth of 35.0 km and coordinates 16.4699°, -97.7421°.
Physical scale: An earthquake of magnitude 4.0 releases seismic energy equivalent to roughly 15 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 347 m — a useful intuition for the size of the slip patch on the fault.
