2026-07-04 16:41:05 UTC (2026-07-04) · approx. 2:41 AM UTC+10 local
On July 4, 2026 at 16:41 UTC, a magnitude 4.1 shallow crustal earthquake struck 110 km SE of Severo-Kuril’sk, Russia, at a depth of 30.1 km and coordinates 49.8762°, 157.0482°.
Physical scale: An earthquake of magnitude 4.1 releases seismic energy equivalent to roughly 21 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 406 m — a useful intuition for the size of the slip patch on the fault.
