On January 20, 2025 at 22:04 UTC, a magnitude 2.1 shallow crustal earthquake struck 7 km ENE of Fall City, Washington, at a depth of 17.2 km and coordinates 47.6002°, -121.7978°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 21.3 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 17 m — a useful intuition for the size of the slip patch on the fault.
