2022-04-18 21:39:04 UTC (2022-04-18) · approx. 7:39 AM UTC+10 local
On April 18, 2022 at 21:39 UTC, a magnitude 4.8 intermediate depth earthquake struck 215 km SW of Severo-Kuril’sk, Russia, at a depth of 130.2 km and coordinates 49.3495°, 153.9310°.
Physical scale: An earthquake of magnitude 4.8 releases seismic energy equivalent to roughly 239 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.2 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.
