On February 11, 2026 at 19:36 UTC, a magnitude 3.0 shallow crustal earthquake struck 71 km SSW of Kaktovik, Alaska, at a depth of 5.0 km and coordinates 69.5060°, -144.0360°.

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.
