Magnitude 5.5 earthquake strikes China's Qinghai province near Yellow River

A magnitude 5.5 earthquake shook parts of the Chinese province of Qinghai on Wednesday, with its epicentre located near the source of the Yellow River, the main natural waterway serving northern China.

The vast Qinghai-Tibetan plateau has been jolted by seismic activity since Tuesday, including a deadly 6.8-magnitude quake in the foothills of the Himalayas in Tibet and a smaller 3.1-magnitude quake in Sichuan.

The epicentre of the Qinghai quake, which struck at 3:44 p.m. (0844 GMT), was located in Madoi county in the Golog prefecture at a depth of 14 km (8.7 miles), according to the China Earthquake Networks Center (CENC).

The epicentre of Qinghai quake on Wednesday is about 1,000 km northeast of the quake in Tibet a day earlier.
