2020-08-12 23:47:31 UTC (2020-08-12) · approx. 4:47 PM UTC-7 local
On August 12, 2020 at 23:47 UTC, a magnitude 2.3 shallow crustal earthquake struck 3 km SSE of Jackson, Wyoming, at a depth of 3.6 km and coordinates 43.4455°, -110.7508°.
Physical scale: An earthquake of magnitude 2.3 releases seismic energy equivalent to roughly 42.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 23 m — a useful intuition for the size of the slip patch on the fault.
