2026-01-05 23:40:30 UTC (2026-01-05) · approx. 1:40 PM UTC-10 local
On January 5, 2026 at 23:40 UTC, a magnitude 3.2 shallow crustal earthquake struck 68 km W of Karluk, Alaska, at a depth of 66.3 km and coordinates 57.6390°, -155.5880°.
Physical scale: An earthquake of magnitude 3.2 releases seismic energy equivalent to roughly 951 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 97 m — a useful intuition for the size of the slip patch on the fault.
