M4.1 Earthquake 99 km ENE of Ouzinkie, Alaska — November 13, 2026
2026-11-13 23:26:18 UTC (15 min ago) · approx. 1:26 PM UTC-10 local
On November 13, 2026 at 23:26 UTC, a magnitude 4.1 shallow crustal earthquake struck 99 km ENE of Ouzinkie, Alaska, at a depth of 21.9 km and coordinates 58.3720°, -151.0490°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
