5.8 quake North Pacific Ocean, Russia, 3 Mar 2021 7:22 am (GMT +10)
A shallow magnitude 5.8 earthquake was reported in the morning near Shikotan, Sakhalin Oblast, Russia.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Wednesday 3 March 2021 at 7:22 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.
Our monitoring service identified a second report from the European-Mediterranean Seismological Centre (EMSC) which listed the quake at magnitude 5.8 as well.
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 Shikotan (pop. 2,100) located 114 km from the epicenter, and Kuril'sk (pop. 1,700) 135 km away.
VolcanoDiscovery will automatically update magnitude and depth if these change and follow up if other significant news about the quake become available. If you’re in the area, please send us your experience through our reporting mechanism, either online or via our mobile app. This will help us provide more first-hand updates to anyone around the globe who wants to know more about this quake.
