On April 29, 2026 at 09:18 UTC, a magnitude 2.8 shallow crustal earthquake struck 43 km NNE of Chickaloon, Alaska, at a depth of 21.7 km and coordinates 62.1770°, -148.2710°.

Physical scale: An earthquake of magnitude 2.8 releases seismic energy equivalent to roughly 239 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 52 m — a useful intuition for the size of the slip patch on the fault.
