On September 17, 2025 at 21:56 UTC, a magnitude 3.6 shallow crustal earthquake struck 48 km W of Mentone, Texas, at a depth of 7.9 km and coordinates 31.7330°, -104.1080°.

Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
