M3.1 Earthquake 22 km SE of Wright, Wyoming — August 30, 2025
2025-08-30 19:30:44 UTC (2025-08-30) · approx. 12:30 PM UTC-7 local
On August 30, 2025 at 19:30 UTC, a magnitude 3.1 shallow crustal earthquake struck 22 km SE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.5998°, -105.3156°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
