M4.9 Earthquake 211 km ESE of Severo-Kuril’sk, Russia — June 21, 2026
2026-06-21 23:04:25 UTC (2026-06-21) · approx. 10:04 AM UTC+11 local
On June 21, 2026 at 23:04 UTC, a magnitude 4.9 shallow crustal earthquake struck 211 km ESE of Severo-Kuril’sk, Russia, at a depth of 10.0 km and coordinates 49.9946°, 158.9050°. This earthquake was detected by 94 seismic stations with good location accuracy and was assigned a USGS significance rating of 369, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.9 releases seismic energy equivalent to roughly 338 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.4 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.
