An earthquake measuring 6.2 struck China’s northwest Qinghai province around 3pm on Monday, according to the China Earthquake Networks Centre (CENC).
The quake struck at 3:14pm at a depth of about 9km, with its epicentre in a remote mountainous area in Zadoi county, Yushu prefecture, CENC said.
The epicentre is situated high on the Qinghai-Tibet plateau at an altitude of 4,700 metres, and is “extremely sparsely populated” in a radius of 20km.
About 12,000 people live within 50km radius of the epicentre, it added.
Strong tremors were felt up to 36km away, but no injuries or building collapses had been reported, according to state broadcaster CCTV.
Schools across Zadoi were suspended and students evacuated, CCTV added.
A series of aftershocks continued to hit the area after the first quake, with the strongest measuring 4.2.
The US Geological Survey said the earthquake had a magnitude of 6.4 and a depth of 32km.
In April 2010, a magnitude 6.9 quake struck adjacent Yushu county, killing 2,700 people and injuring more than 10,000. The quake’s epicentre was close to monastery town of Gyegu, where 85 per cent of mostly timber and earthen buildings were destroyed.
