The epicentre of the quake in Qinghai, which struck at 2:04 am (1804 GMT Friday) at a relatively shallow depth of 10 kilometres (six miles), was located about 400 kliometres southwest of the city of Xining, US seismologists said.

On Tuesday, one of the tallest skyscrapers in China, SEG Plaza at Shenzhen was evacuated after it was seen shaking that horrified the shopkeepers and people around the building, who were later sent to safety. It is a 300-metre high building that began to shake in the afternoon, around 1 pm local time.

Dali is within 10 kilometres of the city of Shenzen.
