On July 17, 2024 at 17:55 UTC, a magnitude 3.6 shallow crustal earthquake struck 113 km ESE of Yakutat, Alaska, at a depth of 10.8 km and coordinates 59.0613°, -137.9833°. The earthquake was reported felt by 2 peopleacross nearby locations, with a maximum shaking intensity of Modified Mercalli Intensity (MMI) 3.5 (light).

Physical scale: An earthquake of magnitude 3.6 releases seismic energy equivalent to roughly 3.8 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 184 m — a useful intuition for the size of the slip patch on the fault.
