M4.6 Earthquake 26 km WSW of Yuzhno-Kurilsk, Russia — October 2, 2020
2020-10-02 23:37:51 UTC (2020-10-02) · approx. 9:37 AM UTC+10 local
On October 2, 2020 at 23:37 UTC, a magnitude 4.6 shallow crustal earthquake struck 26 km WSW of Yuzhno-Kurilsk, Russia, at a depth of 10.5 km and coordinates 43.9028°, 145.5761°.
Physical scale: An earthquake of magnitude 4.6 releases seismic energy equivalent to roughly 120 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 899 m — 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.
