On May 9, 2021 at 23:33 UTC, a magnitude 5.0 shallow crustal earthquake struck near Kuril Islands, at a depth of 65.3 km and coordinates 46.6309°, 152.0442°.

Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 km — a useful intuition for the size of the slip patch on the fault.
