On March 18, 2025 at 18:19 UTC, a magnitude 3.0 shallow crustal earthquake struck 8 km SSE of Sleepy Hollow, Wyoming, at a depth of 0.0 km and coordinates 44.1709°, -105.3672°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
