On August 26, 2025 at 22:03 UTC, a magnitude 3.2 shallow crustal earthquake struck 90 km SE of King Cove, Alaska, at a depth of 29.4 km and coordinates 54.4572°, -161.3738°.

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.
