On September 4, 2022 at 21:51 UTC, a magnitude 2.2 shallow crustal earthquake struck 4 km SSE of Lakesite, Tennessee, at a depth of 19.7 km and coordinates 35.1687°, -85.1042°.

Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 33.4 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 21 m — a useful intuition for the size of the slip patch on the fault.
