On June 28, 2026 at 18:06 UTC, a magnitude 3.1 shallow crustal earthquake struck 91 km SSW of Alberto Oviedo Mota, B.C., MX, at a depth of 7.1 km and coordinates 31.5042°, -115.6225°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 697 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 84 m — a useful intuition for the size of the slip patch on the fault.
