On August 30, 2026 at 13:36 UTC, a magnitude 3.2 shallow crustal earthquake struck 234 km WSW of Adak, Alaska, at a depth of 28.6 km and coordinates 51.3100°, -179.8930°.

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.
