2025-02-11 20:06:44 UTC (2025-02-11) · approx. 1:06 PM UTC-7 local
On February 11, 2025 at 20:06 UTC, a magnitude 3.5 shallow crustal earthquake struck 27 km NE of Ranchester, Wyoming, at a depth of 0.0 km and coordinates 45.1103°, -106.9599°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
