2026-08-10 10:36:42 UTC (1 hour ago) · approx. 8:36 PM UTC+10 local
On August 10, 2026 at 10:36 UTC, a magnitude 4.7 shallow crustal earthquake struck 66 km ENE of Shikotan, Russia, at a depth of 66.1 km and coordinates 44.0156°, 147.4942°. This earthquake was detected by 59 seismic stations with good location accuracy and was assigned a USGS significance rating of 340, placing it among routine seismic activity.
Physical scale: An earthquake of magnitude 4.7 releases seismic energy equivalent to roughly 169 metric tons of TNT. Empirical fault-scaling laws (Wells & Coppersmith, 1994) estimate the subsurface rupture length at approximately 1.1 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.
