2025-05-13 18:20:12 UTC (2025-05-13) · approx. 11:20 AM UTC-7 local
On May 13, 2025 at 18:20 UTC, a magnitude 3.3 shallow crustal earthquake struck 19 km NNE of Vernal, Utah, at a depth of 0.0 km and coordinates 40.6220°, -109.4493°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
