On August 30, 2025 at 19:17 UTC, a magnitude 2.3 shallow crustal earthquake struck 55 km NE of Valmy, Nevada, at a depth of 10.0 km and coordinates 41.1564°, -116.6757°.

Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
