2026-07-16 05:37:56 UTC (16 min ago) · approx. 6:37 PM UTC-11 local
On July 16, 2026 at 05:37 UTC, a magnitude 3.1 shallow crustal earthquake struck 104 km NNW of Aleknagik, Alaska, at a depth of 0.2 km and coordinates 60.0760°, -159.5850°.
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.
