An earthquake of magnitude 5.4 occurred in the morning on Sunday, August 2nd, 2026, at 11:13 am local time near Kasivobara, Sakhalin Oblast, Russia, as reported by the European-Mediterranean Seismological Centre (EMSC).According to preliminary data, the quake was located at a moderately shallow depth of 62. 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 German Research Centre for Geosciences (GFZ) which listed the quake at magnitude 5.4 as well. A third agency, France's Réseau National de Surveillance Sismique (RéNaSS), reported the same quake at magnitude 5.2.Based on the preliminary seismic data, the quake should not have caused any significant damage, but was probably felt by many people as light vibration in the area of the epicenter. Weak shaking might have been felt in Kasivobara (pop. 2,400) located 119 km from the epicenter.VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available.
