2026-09-24 21:34:17 UTC (4 hours ago) · approx. 2:34 PM UTC-7 local
On September 24, 2026 at 21:34 UTC, a magnitude 3.0 shallow crustal earthquake struck 6 km ENE of Superior, Wyoming, at a depth of 13.1 km and coordinates 41.7892°, -108.9087°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 548 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 75 m — a useful intuition for the size of the slip patch on the fault.
