On October 22, 2026 at 16:51 UTC, a magnitude 4.2 shallow crustal earthquake struck 269 km ENE of Dawson City, Canada, at a depth of 10.0 km and coordinates 65.0219°, -134.2798°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
