On September 20, 2026 at 14:17 UTC, a magnitude 3.2 shallow crustal earthquake struck 57 km ENE of Chenega, Alaska, at a depth of 16.0 km and coordinates 60.2160°, -147.0150°.
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.
