On September 14, 2026 at 10:29 UTC, a magnitude 3.3 shallow crustal earthquake struck 116 km SE of Akutan, Alaska, at a depth of 28.1 km and coordinates 53.3150°, -164.6820°.

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.
