On September 12, 2026 at 04:17 UTC, a magnitude 2.6 shallow crustal earthquake struck 2 km E of Mount Vernon, Washington, at a depth of 13.4 km and coordinates 48.4213°, -122.3012°.

Physical scale: An earthquake of magnitude 2.6 releases seismic energy equivalent to roughly 104 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 35 m — a useful intuition for the size of the slip patch on the fault.
