M4.4 Earthquake 20 km W of Preston, Nevada — September 27, 2026
2026-09-27 08:54:07 UTC (1 hour ago) · approx. 12:54 AM UTC-8 local
On September 27, 2026 at 08:54 UTC, a magnitude 4.4 shallow crustal earthquake struck 20 km W of Preston, Nevada, at a depth of 0.0 km and coordinates 38.9229°, -115.2989°. The nearest populated place is Ely (population 3,983).
Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 52 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 614 m — a useful intuition for the size of the slip patch on the fault.
