On January 9, 2025 at 21:42 UTC, a magnitude 4.3 shallow crustal earthquake struck 288 km E of Kuril’sk, Russia, at a depth of 42.4 km and coordinates 45.7192°, 151.4958°.

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.
