2023-03-16 21:42:28 UTC (2023-03-16) · approx. 2:42 PM UTC-7 local
On March 16, 2023 at 21:42 UTC, a magnitude 3.0 shallow crustal earthquake struck 14 km ENE of Point of Rocks, Wyoming, at a depth of 0.0 km and coordinates 41.7395°, -108.6358°.
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.
