2026-10-30 04:46:08 UTC (2026-10-30) · approx. 6:46 PM UTC-10 local
On October 30, 2026 at 04:46 UTC, a magnitude 3.2 intermediate depth earthquake struck 208 km SE of Chiniak, Alaska, at a depth of 75.0 km and coordinates 56.1230°, -150.1990°.
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.
