2025-03-13 19:57:09 UTC (2025-03-13) · approx. 12:57 PM UTC-7 local
On March 13, 2025 at 19:57 UTC, a magnitude 3.4 shallow crustal earthquake struck 21 km NE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.8896°, -105.2990°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
