On July 15, 2026 at 18:56 UTC, a magnitude 3.3 shallow crustal earthquake struck 109 km WNW of Yakutat, Alaska, at a depth of 2.5 km and coordinates 59.8990°, -141.5400°.

Physical scale: An earthquake of magnitude 3.3 releases seismic energy equivalent to roughly 1.3 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 114 m — a useful intuition for the size of the slip patch on the fault.
