On September 19, 2024 at 22:07 UTC, a magnitude 3.8 deep-focus earthquake struck northwest of the Kuril Islands, at a depth of 473.7 km and coordinates 50.5570°, 150.2967°.

Physical scale: An earthquake of magnitude 3.8 releases seismic energy equivalent to roughly 7.6 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 252 m — a useful intuition for the size of the slip patch on the fault.
