On October 24, 2021 at 22:33 UTC, a magnitude 2.5 shallow crustal earthquake struck 2 km NW of McConnell AFB, Kansas, at a depth of 6.5 km and coordinates 37.6489°, -97.2764°.
Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
