On November 21, 2024 at 17:46 UTC, a magnitude 2.9 shallow crustal earthquake struck 14 km E of Fredonia, Arizona, at a depth of 19.4 km and coordinates 36.9460°, -112.3687°. This earthquake was detected by 17 seismic stations with good location accuracy and was assigned a USGS significance rating of 135, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 2.9 releases seismic energy equivalent to roughly 338 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 60 m — a useful intuition for the size of the slip patch on the fault.
