2022-02-28 19:13:23 UTC (2022-02-28) · approx. 12:13 PM UTC-7 local
On February 28, 2022 at 19:13 UTC, a magnitude 2.7 shallow crustal earthquake struck 4 km S of Joseph, Utah, at a depth of -2.9 km and coordinates 38.5822°, -112.2097°.
Physical scale: An earthquake of magnitude 2.7 releases seismic energy equivalent to roughly 169 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 44 m — a useful intuition for the size of the slip patch on the fault.
