4.8 quake 16 Apr 12:42 am (GMT +8)
A shallow magnitude 4.8 earthquake was reported after midnight near Turt, Khankh, Hövsgöl Aymag, Mongolia.
According to the German Research Centre for Geosciences (GFZ), the quake hit on Friday 16 April 2021 at 12:42 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 4.8 as well.
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 Turt (pop. 2,100) located 25 km from the epicenter, the quake should have been felt as light shaking.
