The United States Geological Survey reported a magnitude 6.0 quake in Russia near Severo-Kuril’sk, Sakhalin Oblast, only 19 minutes ago. The earthquake hit early afternoon on Wednesday, August 27th, 2025, at 2:49 pm local time at a moderately shallow depth of 53.41 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.
A second report was later issued by Italy’s National Institute of Geophysics and Volcanology (INGV), which listed it as a magnitude 6.1 earthquake. Other agencies reporting the same quake include the European-Mediterranean Seismological Centre (EMSC) at magnitude 6.0, The Geophysical Survey of the Russian Academy of Sciences (KB-GS-RAS) at magnitude 6.2, the citizen-seismograph network of RaspberryShake at magnitude 5.8, France’s Réseau National de Surveillance Sismique (RéNaSS) at magnitude 5.8, and the German Research Centre for Geosciences (GFZ) at magnitude 5.9.
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
