2023-02-18 20:20:59 UTC (2023-02-18) · approx. 1:20 PM UTC-7 local
On February 18, 2023 at 20:20 UTC, a magnitude 3.2 shallow crustal earthquake struck 25 km SE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.6148°, -105.2392°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
