On September 18, 2026 at 10:34 UTC, a magnitude 3.2 shallow crustal earthquake struck 70 km SSW of Kaktovik, Alaska, at a depth of 2.7 km and coordinates 69.5310°, -144.1820°.
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.
