On January 6, 2026 at 18:25 UTC, a magnitude 4.2 intermediate depth earthquake struck 58 km SSE of Vilyuchinsk, Russia, at a depth of 86.9 km and coordinates 52.4528°, 158.7552°.

Physical scale: An earthquake of magnitude 4.2 releases seismic energy equivalent to roughly 30 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 476 m — a useful intuition for the size of the slip patch on the fault.
