On November 4, 2026 at 03:17 UTC, a magnitude 3.4 intermediate depth earthquake struck 31 km SSE of Skwentna, Alaska, at a depth of 83.1 km and coordinates 61.7330°, -151.1610°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
