Felt by 226 people across surrounding communities.
On July 25, 2020 at 23:29 UTC, a magnitude 2.5 shallow crustal earthquake struck 4 km NE of Magna, Utah, at a depth of 10.5 km and coordinates 40.7343°, -112.0567°. This earthquake was detected by 40 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 172, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 97.4 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 34 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.
