On July 22, 2026 at 22:30 UTC, a magnitude 2.1 shallow crustal earthquake struck 5 km WSW of Yacolt, Washington, at a depth of -0.6 km and coordinates 45.8413°, -122.4617°.

Physical scale: An earthquake of magnitude 2.1 releases seismic energy equivalent to roughly 24.5 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.
