2026-07-28 17:01:00 UTC (1 day ago) · approx. 6:01 AM UTC-11 local
On July 28, 2026 at 17:01 UTC, a magnitude 3.1 shallow crustal earthquake struck 264 km SSE of King Cove, Alaska, at a depth of 29.3 km and coordinates 52.7910°, -161.1100°.
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.
