2026-08-02 16:42:56 UTC (6 days ago) · approx. 5:42 AM UTC-11 local
On August 2, 2026 at 16:42 UTC, a magnitude 3.3 intermediate depth earthquake struck 35 km ESE of King Cove, Alaska, at a depth of 103.8 km and coordinates 54.9920°, -161.7820°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
