On March 15, 2021 at 18:55 UTC, a magnitude 4.4 intermediate depth earthquake struck 24 km NE of Niños Héroes, Mexico, at a depth of 178.9 km and coordinates 17.5701°, -94.3149°.
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.
