At least 111 people have been killed and another 220 injured following an earthquake on Monday night in north-west China.
State media reports that a 5.9 magnitude earthquake struck Gansu province around midnight, bringing down buildings there and in Qinghai province to the south.
Emergency workers are braving freezing conditions to try and help people in the high-altitude area.
A second quake struck Xinjiang hours later on Tuesday.
The damage from that 5.5-magnitude strike was not immediately clear.
Chinese President Xi Jinping has ordered full rescue efforts to Gansu, one of China's poorest regions.
Gansu lies between the Tibetan and Loess plateaus and borders Mongolia. The Monday night quake struck the Linxia Hui Autonomous Prefecture, an administrative region for China's Muslim Hui people.
The US Geological Survey (USGS) said it had a magnitude of 5.9 and a depth of 10km (six miles).
Footage showed hospitals receiving patients and rescuers searching through the rubble of collapsed buildings. Debris was also seen on the floors of rooms whose ceilings had partially collapsed.
