2026-11-03 00:34:06 UTC (1 hour ago) · approx. 1:34 PM UTC-11 local
On November 3, 2026 at 00:34 UTC, a magnitude 3.0 shallow crustal earthquake struck 51 km E of Chignik, Alaska, at a depth of 47.6 km and coordinates 56.3000°, -157.5660°.
Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
