On August 11, 2026 at 07:08 UTC, a magnitude 3.0 shallow crustal earthquake struck near Rat Islands, Aleutian Islands, Alaska, at a depth of 10.0 km and coordinates 50.3760°, 176.7078°.

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.
