2020-10-08 18:24:52 UTC (2020-10-08) · approx. 4:24 AM UTC+10 local
On October 8, 2020 at 18:24 UTC, a magnitude 5.0 deep-focus earthquake struck 293 km WNW of Ozernovskiy, Russia, at a depth of 523.6 km and coordinates 52.6525°, 152.6467°.
Physical scale: An earthquake of magnitude 5.0 releases seismic energy equivalent to roughly 477 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.7 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.
