On February 10, 2021 at 22:34 UTC, a magnitude 4.3 shallow crustal earthquake struck 62 km E of Shikotan, Russia, at a depth of 58.3 km and coordinates 43.7917°, 147.4977°.
Physical scale: An earthquake of magnitude 4.3 releases seismic energy equivalent to roughly 43 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 558 m — a useful intuition for the size of the slip patch on the fault.
