On May 3, 2026 at 02:22 UTC, a magnitude 3.1 intermediate depth earthquake struck 67 km SE of Pedro Bay, Alaska, at a depth of 110.2 km and coordinates 59.3590°, -153.2510°.

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.
