2021-06-06 16:01:41 UTC (2021-06-06) · approx. 2:01 AM UTC+10 local
On June 6, 2021 at 16:01 UTC, a magnitude 5.1 shallow crustal earthquake struck 90 km ESE of Severo-Kuril’sk, Russia, at a depth of 57.4 km and coordinates 50.2748°, 157.2415°.
Physical scale: An earthquake of magnitude 5.1 releases seismic energy equivalent to roughly 674 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 2.0 km — a useful intuition for the size of the slip patch on the fault.
The epicenter is located in Russia, a region characterized by the Kuril-Kamchatka subduction zone on the northwestern Pacific Ring of Fire. The nearest mapped fault system is the Kuril-Kamchatka Trench. View all earthquakes in Russia.
