On September 27, 2026 at 07:02 UTC, a magnitude 3.5 shallow crustal earthquake struck 41 km SW of Deseret, Utah, at a depth of 0.0 km and coordinates 38.9967°, -112.9638°. The earthquake was reported felt by 1 personacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.3 (light).

Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 159 m — a useful intuition for the size of the slip patch on the fault.
