2021-04-13 21:15:42 UTC (2021-04-13) · approx. 2:15 PM UTC-7 local
On April 13, 2021 at 21:15 UTC, a magnitude 3.0 shallow crustal earthquake struck 18 km NNE of Maeser, Utah, at a depth of 0.0 km and coordinates 40.6346°, -109.5178°.
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.
