On June 15, 2024 at 21:27 UTC, a magnitude 3.1 shallow crustal earthquake struck 109 km SSE of Yakutat, Alaska, at a depth of 7.3 km and coordinates 58.7050°, -138.7328°.

Physical scale: An earthquake of magnitude 3.1 releases seismic energy equivalent to roughly 674 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 83 m — a useful intuition for the size of the slip patch on the fault.
