2022-11-22 20:49:33 UTC (2022-11-22) · approx. 7:49 AM UTC+11 local
On November 22, 2022 at 20:49 UTC, a magnitude 4.5 shallow crustal earthquake struck near near the east coast of the Kamchatka Peninsula, Russia, at a depth of 44.1 km and coordinates 55.6035°, 162.5760°. This earthquake was detected by 182 seismic stations with excellent location accuracy and was assigned a USGS significance rating of 312, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.5 releases seismic energy equivalent to roughly 85 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 767 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.
