2026-10-16 00:37:55 UTC (20 hours ago) · approx. 1:37 PM UTC-11 local
On October 16, 2026 at 00:37 UTC, a magnitude 3.1 shallow crustal earthquake struck 95 km SSE of Akutan, Alaska, at a depth of 19.2 km and coordinates 53.3630°, -165.1460°.
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.
