On November 16, 2023 at 18:33 UTC, a magnitude 2.1 shallow crustal earthquake struck 4 km SE of Benton City, Washington, at a depth of -0.3 km and coordinates 46.2415°, -119.4458°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 25.3 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.
