On December 5, 2022 at 23:10 UTC, a magnitude 2.6 shallow crustal earthquake struck 4 km SW of Madison, Missouri, at a depth of 1.4 km and coordinates 39.4442°, -92.2527°.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 116 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 37 m — a useful intuition for the size of the slip patch on the fault.
