On April 23, 2026 at 19:30 UTC, a magnitude 2.1 shallow crustal earthquake struck 1 km WNW of Cooter, Missouri, at a depth of 10.3 km and coordinates 36.0510°, -89.8265°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 24.5 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 18 m — a useful intuition for the size of the slip patch on the fault.
