2026-09-27 07:18:53 UTC (1 hour ago) · approx. 11:18 PM UTC-8 local
On September 27, 2026 at 07:18 UTC, a magnitude 3.5 shallow crustal earthquake struck 21 km W of Preston, Nevada, at a depth of 3.9 km and coordinates 38.9253°, -115.3111°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 145 m — a useful intuition for the size of the slip patch on the fault.
