2026-02-26 18:56:11 UTC (2026-02-26) · approx. 5:56 AM UTC+11 local
On February 26, 2026 at 18:56 UTC, a magnitude 4.6 shallow crustal earthquake struck 210 km SE of Vilyuchinsk, Russia, at a depth of 10.0 km and coordinates 51.5180°, 160.4590°. This earthquake was detected by 51 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.
