On September 11, 2025 at 22:26 UTC, a magnitude 2.9 shallow crustal earthquake struck 40 km S of Qualeys Camp, NV, at a depth of 12.8 km and coordinates 37.9447°, -118.5377°.

Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 315 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 59 m — a useful intuition for the size of the slip patch on the fault.
