2023-12-31 19:10:31 UTC (2023-12-31) · approx. 12:10 PM UTC-7 local
On December 31, 2023 at 19:10 UTC, a magnitude 3.0 shallow crustal earthquake struck 22 km NNW of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.9307°, -105.6158°.
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.
