On August 25, 2025 at 17:20 UTC, a magnitude 3.0 intermediate depth earthquake struck near Rat Islands, Aleutian Islands, Alaska, at a depth of 97.2 km and coordinates 51.8365°, 178.2986°.

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.
