On August 5, 2024 at 20:50 UTC, a magnitude 3.0 intermediate depth earthquake struck 58 km NNE of Petersville, Alaska, at a depth of 97.9 km and coordinates 62.9707°, -150.2933°.

Physical scale: An earthquake of magnitude 3.0 releases seismic energy equivalent to roughly 477 kg of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 71 m — a useful intuition for the size of the slip patch on the fault.
