On September 14, 2026 at 20:45 UTC, a magnitude 4.3 shallow crustal earthquake struck 177 km SSE of Vilyuchinsk, Russia, at a depth of 37.5 km and coordinates 51.5240°, 159.6317°.
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.
