M3.0 Earthquake 14 km ENE of Wright, Wyoming — October 19, 2021
2021-10-19 19:58:46 UTC (2021-10-19) · approx. 12:58 PM UTC-7 local
On October 19, 2021 at 19:58 UTC, a magnitude 3.0 shallow crustal earthquake struck 14 km ENE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.7915°, -105.3159°.
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.
