A shallow magnitude 5.2 earthquake was reported in the morning near Shikotan, Sakhalin Oblast, Russia.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Thursday, August 21st, 2025, at 8:24 am local time at a shallow depth of 10. km. Shallow earthquakes are felt more strongly than deeper ones as they are closer to the surface. 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 France’s Réseau National de Surveillance Sismique (RéNaSS), which listed it as a magnitude 5.2 earthquake as well. A third agency, the citizen-seismograph network of RaspberryShake, reported the same quake at magnitude 5.2.
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 Shikotan (pop. 2,100) located 49 km from the epicenter, the quake should have been felt as light shaking.
Weak shaking might have been felt in Yuzhno-Kurilsk (pop. 7,800) located 122 km from the epicenter.
