On September 25, 2025 at 20:20 UTC, a magnitude 3.3 shallow crustal earthquake struck 80 km SSW of Alberto Oviedo Mota, B.C., MX, at a depth of 7.5 km and coordinates 31.5965°, -115.5797°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 110 m — a useful intuition for the size of the slip patch on the fault.
