M3.3 Earthquake 17 km ENE of Wright, Wyoming — April 20, 2023
2023-04-20 18:04:34 UTC (2023-04-20) · approx. 11:04 AM UTC-7 local
On April 20, 2023 at 18:04 UTC, a magnitude 3.3 shallow crustal earthquake struck 17 km ENE of Wright, Wyoming, at a depth of 0.0 km and coordinates 43.7853°, -105.2754°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
