On January 9, 2024 at 15:17 UTC, a magnitude 2.4 shallow crustal earthquake struck 13 km NNE of Ashford, Washington, at a depth of 6.4 km and coordinates 46.8628°, -121.9323°.

Physical scale: An earthquake of magnitude 2.4 releases seismic energy equivalent to roughly 54.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 26 m — a useful intuition for the size of the slip patch on the fault.
