2025-11-01 22:26:25 UTC (2025-11-01) · approx. 8:26 AM UTC+10 local
On November 1, 2025 at 22:26 UTC, a magnitude 4.3 intermediate depth earthquake struck 26 km SE of Severo-Kuril’sk, Russia, at a depth of 93.0 km and coordinates 50.5114°, 156.3963°.
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.
