2026-07-31 17:15:40 UTC (4 hours ago) · approx. 6:15 AM UTC-11 local
On July 31, 2026 at 17:15 UTC, a magnitude 3.2 shallow crustal earthquake struck 85 km SE of King Cove, Alaska, at a depth of 35.0 km and coordinates 54.4289°, -161.5590°.
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.
