M3.5 Earthquake 12 km ENE of Wright, Wyoming — November 20, 2020
2020-11-20 21:05:09 UTC (2020-11-20) · approx. 2:05 PM UTC-7 local
On November 20, 2020 at 21:05 UTC, a magnitude 3.5 shallow crustal earthquake struck 12 km ENE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.7884°, -105.3482°.
Physical scale: An earthquake of magnitude 3.5 releases seismic energy equivalent to roughly 2.7 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 157 m — a useful intuition for the size of the slip patch on the fault.
