On September 24, 2022 at 20:15 UTC, a magnitude 3.1 intermediate depth earthquake struck 63 km ESE of Denali National Park, Alaska, at a depth of 125.9 km and coordinates 63.2359°, -150.6530°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
