2021-12-07 21:12:43 UTC (2021-12-07) · approx. 2:12 PM UTC-7 local
On December 7, 2021 at 21:12 UTC, a magnitude 3.1 shallow crustal earthquake struck 17 km ESE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.6758°, -105.2972°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
