2026-10-09 22:39:39 UTC (3 days ago) · approx. 11:39 AM UTC-11 local
On October 9, 2026 at 22:39 UTC, a magnitude 3.0 shallow crustal earthquake struck 98 km SSE of King Cove, Alaska, at a depth of 3.0 km and coordinates 54.2590°, -161.6810°.
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.
