Felt by 4 people across nearby locations.
On October 22, 2021 at 23:03 UTC, a magnitude 5.0 shallow crustal earthquake struck near southwestern Siberia, Russia, at a depth of 10.0 km and coordinates 51.4199°, 91.8033°.
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.
