M3.2 Earthquake 87 km SE of Atka, Alaska — November 6, 2026
2026-11-06 20:32:58 UTC (5 days ago) · approx. 8:32 AM UTC-12 local
On November 6, 2026 at 20:32 UTC, a magnitude 3.2 shallow crustal earthquake struck 87 km SE of Atka, Alaska, at a depth of 33.6 km and coordinates 51.7130°, -173.1940°.
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.
