A 6.8-magnitude earthquake hit eastern Tajikistan at a depth of about 20.5 km on Thursday.
The US Geological Survey estimated that little or no population will be exposed to landslides from the quake, adding that a 5.0-magnitude aftershock hit the area about 20 minutes after the initial quake.
It revealed that its epicenter appeared to be in a semi-autonomous eastern region that borders Afghanistan and China.
The sparsely populated territory is surrounded by the towering Pamir Mountains.
