On March 26, 2024 at 17:09 UTC, a magnitude 2.5 shallow crustal earthquake struck 27 km S of Morton, Washington, at a depth of 4.6 km and coordinates 46.3158°, -122.2247°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 87.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 33 m — a useful intuition for the size of the slip patch on the fault.
