On June 18, 2026 at 12:21 UTC, a magnitude 3.2 shallow crustal earthquake struck 44 km NNW of Valdez, Alaska, at a depth of 19.4 km and coordinates 61.5180°, -146.5780°.

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.
