Significant earthquake of magnitude 6.0 just reported 89 km southeast of Sovetskaya Gavan’, Russia

6.0 quake 1 Dec 7:54 am (GMT +9)
6.0 quake 1 Dec 7:54 am (GMT +9)
A very deep magnitude 6.0 earthquake was reported in the morning near Sovetskaya Gavan', Russia.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Tuesday 1 December 2020 at 7.54 am local time at a great depth of 585 km. The strength of the earthquake may have been tempered by its relative great depth below the surface, which makes it feel weaker in absolute terms. 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 United States Geological Survey (USGS) which listed the quake at magnitude 6.4. Other agencies reporting the same quake include Geoscience Australia (GeoAu) at magnitude 6.4, Italy's National Institute of Geophysics and Volcanology (INGV) at magnitude 6.3, and European-Mediterranean Seismological Centre (EMSC) at magnitude 6.0.
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.Towns or cities near the epicenter where the quake might have been felt as very weak shaking include Sovetskaya Gavan'(pop. 29,700) located 89 km from the epicenter, Vanino (pop. 18,600) 103 km away, Uglegorsk (pop. 12,700) 133 km away, and Shakhtersk (pop. 10,100) 144 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.
