2026-07-20 19:14:31 UTC (8 hours ago) · approx. 6:14 AM UTC+11 local
On July 20, 2026 at 19:14 UTC, a magnitude 4.2 shallow crustal earthquake struck 140 km SE of Severo-Kuril’sk, Russia, at a depth of 10.0 km and coordinates 49.9683°, 157.7557°.
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.
