On August 7, 2020 at 03:41 UTC, a magnitude 4.9 intermediate depth earthquake struck 70 km SE of Vilyuchinsk, Russia, at a depth of 79.3 km and coordinates 52.4192°, 159.0138°.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
