On January 28, 2026 at 20:35 UTC, a magnitude 3.0 intermediate depth earthquake struck 55 km NE of Akutan, Alaska, at a depth of 180.0 km and coordinates 54.4693°, -165.1398°.

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.
