2026-08-22 08:14:30 UTC (2 days ago) · approx. 9:14 PM UTC-11 local
On August 22, 2026 at 08:14 UTC, a magnitude 3.1 shallow crustal earthquake struck 93 km SE of King Cove, Alaska, at a depth of 7.3 km and coordinates 54.4300°, -161.3540°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
