On September 23, 2026 at 01:44 UTC, a magnitude 4.4 shallow crustal earthquake struck near Kuril Islands, at a depth of 46.2 km and coordinates 46.8489°, 152.9319°.

Physical scale: An earthquake of magnitude 4.4 releases seismic energy equivalent to roughly 60 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 655 m — a useful intuition for the size of the slip patch on the fault.
