On June 24, 2020 at 23:33 UTC, a magnitude 3.1 shallow crustal earthquake struck 10 km N of Moccasin, Arizona, at a depth of 20.8 km and coordinates 37.0002°, -112.7440°. This earthquake was detected by 16 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 157, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 697 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 84 m — a useful intuition for the size of the slip patch on the fault.
