On April 18, 2026 at 19:09 UTC, a magnitude 2.2 shallow crustal earthquake struck 19 km W of Point MacKenzie, Alaska, at a depth of 29.4 km and coordinates 61.3570°, -150.3460°.

Physical scale: An earthquake of magnitude 2.2 releases seismic energy equivalent to roughly 30.1 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 20 m — a useful intuition for the size of the slip patch on the fault.
