On October 24, 2025 at 20:11 UTC, a magnitude 4.3 shallow crustal earthquake struck 189 km SSE of Vilyuchinsk, Russia, at a depth of 32.9 km and coordinates 51.4935°, 159.8820°.

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.
