M3.1 Earthquake near Utah — February 2, 2023
2023-02-02 21:52:59 UTC (2023-02-02) · approx. 2:52 PM UTC-7 local
On February 2, 2023 at 21:52 UTC, a magnitude 3.1 shallow crustal earthquake struck near Utah, at a depth of 0.0 km and coordinates 40.6383°, -109.4868°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
