M3.1 Earthquake 16 km E of Wright, Wyoming — October 3, 2023
2023-10-03 19:58:33 UTC (2023-10-03) · approx. 12:58 PM UTC-7 local
On October 3, 2023 at 19:58 UTC, a magnitude 3.1 shallow crustal earthquake struck 16 km E of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.7458°, -105.2891°.
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.
