2023-01-23 19:01:00 UTC (2023-01-23) · approx. 12:01 PM UTC-7 local
On January 23, 2023 at 19:01 UTC, a magnitude 4.1 shallow crustal earthquake struck 11 km E of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.7513°, -105.3537°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
