On December 19, 2020 at 21:12 UTC, a magnitude 2.2 shallow crustal earthquake struck 4 km NE of Eastborough, Kansas, at a depth of 5.3 km and coordinates 37.7159°, -97.2263°.

Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 30.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 20 m — a useful intuition for the size of the slip patch on the fault.
