On June 20, 2025 at 20:45 UTC, a magnitude 2.7 shallow crustal earthquake struck 78 km NE of Tonopah, Nevada, at a depth of 0.0 km and coordinates 38.4724°, -116.4928°.

Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 m — a useful intuition for the size of the slip patch on the fault.
