2026-02-18 23:36:44 UTC (2026-02-18) · approx. 9:36 AM UTC+10 local
On February 18, 2026 at 23:36 UTC, a magnitude 4.8 intermediate depth earthquake struck 182 km SSW of Severo-Kuril’sk, Russia, at a depth of 82.2 km and coordinates 49.2644°, 154.8256°. This earthquake was detected by 140 seismic stations with good location accuracy and was assigned a USGS significance rating of 354, placing it among routine seismic activity.
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.
