2022-03-29 21:11:26 UTC (2022-03-29) · approx. 2:11 PM UTC-7 local
On March 29, 2022 at 21:11 UTC, a magnitude 3.3 shallow crustal earthquake struck 10 km NNW of Ryan Park, Wyoming, at a depth of 5.0 km and coordinates 41.4014°, -106.5744°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
