2023-12-30 20:38:48 UTC (2023-12-30) · approx. 1:38 PM UTC-7 local
On December 30, 2023 at 20:38 UTC, a magnitude 3.4 shallow crustal earthquake struck 25 km ESE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.6927°, -105.1918°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
