2026-10-06 00:57:31 UTC (1 day ago) · approx. 1:57 PM UTC-11 local
On October 6, 2026 at 00:57 UTC, a magnitude 3.3 shallow crustal earthquake struck 77 km SE of Akutan, Alaska, at a depth of 38.2 km and coordinates 53.6140°, -164.9960°.
Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
