On February 13, 2026 at 19:45 UTC, a magnitude 3.3 intermediate depth earthquake struck 72 km ESE of Denali National Park, Alaska, at a depth of 126.1 km and coordinates 63.2250°, -150.4560°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
