On June 27, 2023 at 23:28 UTC, a magnitude 4.4 shallow crustal earthquake struck near Kuril Islands, at a depth of 66.1 km and coordinates 47.5921°, 153.7343°.

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.
