Chinese authorities face a race against time to shelter earthquake victims from freezing winter temperatures. The deadliest earthquake in years struck the border of Gansu and Qinghai provinces, killing at least 135 people. The aid operation is challenging due to the severe December weather. Swathes of China are experiencing record-breaking cold temperatures, with the government providing blue tents for shelter. Thousands of relief workers are setting up facilities for the displaced, but long-term resettlement is a problem. The earthquake was the deadliest in China since 2014.
