On October 11, 2023 at 19:59 UTC, a magnitude 3.3 shallow crustal earthquake struck 9 km E of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.7518°, -105.3746°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
