On June 1, 2025 at 23:16 UTC, a magnitude 4.2 shallow crustal earthquake struck 94 km S of San Francisco del Mar Viejo, Mexico, at a depth of 50.1 km and coordinates 15.3789°, -94.5506°.

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.
