On December 23, 2022 at 22:09 UTC, a magnitude 2.6 shallow crustal earthquake struck 3 km SSE of Trenton, Utah, at a depth of 8.0 km and coordinates 41.8842°, -111.9327°. This earthquake was detected by 32 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 114, placing it among routine seismic activity.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 138 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 40 m — a useful intuition for the size of the slip patch on the fault.

The epicenter is located in Utah, a region characterized by the Wasatch Fault zone at the eastern margin of the Basin and Range Province, where east-west extension produces normal-fault earthquakes. The nearest mapped fault system is the Wasatch Fault. View all earthquakes in Utah.
