On September 10, 2026 at 02:22 UTC, a magnitude 3.6 shallow crustal earthquake struck 16 km ESE of Denali National Park, Alaska, at a depth of 5.0 km and coordinates 63.5110°, -151.4070°.

Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
