M4.1 Earthquake 20 km WSW of Gerlach, Nevada — September 16, 2026
2026-09-16 07:17:25 UTC (1 hour ago) · approx. 11:17 PM UTC-8 local
On September 16, 2026 at 07:17 UTC, a magnitude 4.1 shallow crustal earthquake struck 20 km WSW of Gerlach, Nevada, at a depth of 6.9 km and coordinates 40.6069°, -119.5899°. The earthquake was reported felt by 4 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 4.5 (moderate). The nearest populated place is Herlong (population 1,307).
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 400 m — a useful intuition for the size of the slip patch on the fault.
