On September 6, 2026 at 18:31 UTC, a magnitude 4.3 shallow crustal earthquake struck 24 km NE of Ust’-Kamchatsk Staryy, Russia, at a depth of 27.8 km and coordinates 56.3841°, 162.7486°.
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.
