On October 10, 2023 at 15:41 UTC, a magnitude 4.4 intermediate depth earthquake struck near Kuril Islands, at a depth of 125.2 km and coordinates 47.6069°, 152.6784°.

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.
