On June 29, 2026 at 01:27 UTC, a magnitude 2.5 shallow crustal earthquake struck 8 km ESE of Clam Gulch, Alaska, at a depth of 57.4 km and coordinates 60.2090°, -151.2480°.

Physical scale: An earthquake of magnitude 2.5 releases seismic energy equivalent to roughly 84.8 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 32 m — a useful intuition for the size of the slip patch on the fault.
