2022-11-21 20:15:26 UTC (2022-11-21) · approx. 6:15 AM UTC+10 local
On November 21, 2022 at 20:15 UTC, a magnitude 4.6 shallow crustal earthquake struck 199 km E of Kuril’sk, Russia, at a depth of 58.4 km and coordinates 45.3253°, 150.4147°. This earthquake was detected by 59 seismic stations with good location accuracy and was assigned a USGS significance rating of 326, placing it among routine seismic activity.
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.
