2025-11-28 17:39:40 UTC (2025-11-28) · approx. 7:39 AM UTC-10 local
On November 28, 2025 at 17:39 UTC, a magnitude 3.0 intermediate depth earthquake struck 60 km W of Karluk, Alaska, at a depth of 76.2 km and coordinates 57.5930°, -155.4620°.
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.
