On June 15, 2026 at 12:26 UTC, a magnitude 3.2 shallow crustal earthquake struck 229 km ESE of Attu Station, Alaska, at a depth of 5.0 km and coordinates 52.0260°, 176.2790°.

Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
