On October 28, 2025 at 17:15 UTC, a magnitude 3.0 shallow crustal earthquake struck 44 km SE of Denali National Park, Alaska, at a depth of 0.0 km and coordinates 63.2645°, -151.0773°.0

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
