2026-11-03 00:27:57 UTC (1 hour ago) · approx. 2:27 PM UTC-10 local
On November 3, 2026 at 00:27 UTC, a magnitude 3.4 shallow crustal earthquake struck 86 km W of Akhiok, Alaska, at a depth of 25.3 km and coordinates 56.8720°, -155.5910°.
Physical scale: An earthquake of magnitude 3.4 releases seismic energy equivalent to roughly 1.9 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 134 m — a useful intuition for the size of the slip patch on the fault.
