On June 22, 2026 at 02:47 UTC, a magnitude 3.0 shallow crustal earthquake struck 141 km SSE of Alcan Border, Alaska, at a depth of 5.0 km and coordinates 61.5182°, -140.0275°.

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.
