2026-07-31 02:21:20 UTC (40 min ago) · approx. 6:21 PM UTC-8 local
On July 31, 2026 at 02:21 UTC, a magnitude 2.7 shallow crustal earthquake struck 35 km SE of Alamo, Nevada, at a depth of 15.6 km and coordinates 37.1643°, -114.8464°.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 175 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 45 m — a useful intuition for the size of the slip patch on the fault.
