On December 26, 2021 at 21:01 UTC, a magnitude 3.0 shallow crustal earthquake struck near Wyoming, at a depth of 0.0 km and coordinates 43.8511°, -105.1926°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
