On June 13, 2026 at 09:57 UTC, a magnitude 3.3 intermediate depth earthquake struck 30 km SSE of Skwentna, Alaska, at a depth of 80.3 km and coordinates 61.7560°, -151.1030°.

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.
