On August 29, 2022 at 22:14 UTC, a magnitude 4.1 shallow crustal earthquake struck 72 km SSE of Shikotan, Russia, at a depth of 41.4 km and coordinates 43.2401°, 147.1951°.

Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
