2026-09-30 10:31:47 UTC (44 min ago) · approx. 12:31 AM UTC-10 local
On September 30, 2026 at 10:31 UTC, a magnitude 3.1 shallow crustal earthquake struck 26 km N of Glacier View, Alaska, at a depth of 20.8 km and coordinates 62.0480°, -147.6350°.
Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
