On July 31, 2020 at 18:58 UTC, a magnitude 3.2 shallow crustal earthquake struck 26 km SSE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.5474°, -105.3216°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
