An earthquake of about 6.8 magnitude shook eastern Tajikistan at 5:37 a.m. (0037 GMT) on Thursday, Tajik authorities said, which was felt in China and other neighbouring countries, APA reports citing Reuters.
The earthquake struck the mountainous Gorno-Badakhshan autonomous region which was earlier this month hit by a series of deadly avalanches. Although sparsely populated, it is home to a large lake, Sarez, which if disturbed could flood a vast area spanning several countries.
Tajik authorities said there was no sign of the lake being disturbed by the earthquake.
The epicentre was about 82 kms (50.95 miles) from the nearest border with China and the earthquake was strongly felt in some areas in China's western Xinjiang region, including Kashgar and Artux, Chinese state television CCTV reported, putting its magnitude at 7.2.
