On August 26, 2022 at 21:25 UTC, a magnitude 3.0 shallow crustal earthquake struck 23 km SSW of Mammoth, Wyoming, at a depth of 8.8 km and coordinates 44.7820°, -110.8053°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 529 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 74 m — a useful intuition for the size of the slip patch on the fault.
