2026-10-30 18:01:10 UTC (3 hours ago) · approx. 4:01 AM UTC+10 local
On October 30, 2026 at 18:01 UTC, a magnitude 4.5 shallow crustal earthquake struck 236 km ESE of Zyryanka, Russia, at a depth of 10.0 km and coordinates 65.0985°, 155.7595°. This earthquake was detected by 90 seismic stations with good 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.
