An intermediate magnitude 6.0 earthquake was reported in the morning near Severo-Kuril'sk, Sakhalin Oblast, Russia.

According to the European-Mediterranean Seismological Centre (EMSC), the quake hit on Wednesday, November 5th, 2025, at 10:49 am local time at an intermediate depth of 76. km. The exact magnitude, epicenter, and depth of the quake might be revised within the next few hours or minutes as seismologists review data and refine their calculations, or as other agencies issue their report.

Our monitoring service identified a second report from The Geophysical Survey of the Russian Academy of Sciences (KB-GS-RAS) which listed the quake at magnitude 6.0 as well. Other agencies reporting the same quake include France's Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.4, the citizen-seismograph network of RaspberryShake at magnitude 5.7, and the German Research Centre for Geosciences (GFZ) at magnitude 5.7.

Generally quakes of this magnitude are recorded by more than one agency and the results can vary, with subsequent reports that come in after the first one often showing more accuracy.

Based on the preliminary seismic data, the quake was probably felt by many people in the area of the epicenter. It should not have caused significant damage, other than objects falling from shelves, broken windows, etc.

In Severo-Kuril'sk (pop. 2,400) located 112 km from the epicenter, the quake should have been felt as light shaking.
