On July 29, 2026 at 18:05 UTC, a magnitude 3.0 shallow crustal earthquake struck 288 km SSE of King Cove, Alaska, at a depth of 17.1 km and coordinates 52.5477°, -161.2186°.

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.
