On October 8, 2026 at 11:12 UTC, a magnitude 3.0 intermediate depth earthquake struck 65 km NNE of Akutan, Alaska, at a depth of 218.1 km and coordinates 54.6820°, -165.3950°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
