M3.5 Earthquake 1 km NW of Little America, Wyoming — July 14, 2026
2026-07-14 14:24:15 UTC (6 hours ago) · approx. 7:24 AM UTC-7 local
On July 14, 2026 at 14:24 UTC, a magnitude 3.5 shallow crustal earthquake struck 1 km NW of Little America, Wyoming, at a depth of -2.9 km and coordinates 41.5535°, -109.8750°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.7 (light).
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 147 m — a useful intuition for the size of the slip patch on the fault.
