One of China’s tallest skyscrapers was evacuated on Tuesday after it began to shake, sending panicked shoppers scampering to safety. The nearly 300-metre (980ft) SEG Plaza in Shenzhen, southern China, inexplicably began to shake at about 1pm, prompting an evacuation of people inside while pedestrians looked on open-mouthed. The building was closed by 2.40pm, according to local media reports
