Nineteen people, including six tourists, were killed and 247 injured when a 7.0 magnitude earthquake struck a remote, mountainous part Sichuan in China's southwest.
The quake hit a sparsely populated area 200 km (120 miles) northwest of the city of Guangyuan late on Tuesday at a depth of 10 km (6 miles), the U.S. Geological Survey said.
Xinhua news agency said a total of 19 people had been killed and that as many as 31,500 tourists had been evacuated from the quake zone. A French man and a Canadian woman suffered light injuries
A separate quake with a magnitude of 6.6 struck a remote part of China's far northwestern region of Xinjiang on Wednesday morning, the Chinese earthquake administration said. There were no immediate reports of casualties there.
The Xinjiang quake's epicentre was in Jinghe county, about 100 km (60 miles) from the border with Kazakhstan, where about 140,000 people live, according to Xinhua.
Residents several hundred kilometres away in Urumqi, and the cities of Karamay and Yining, felt strong tremors. The jolt lasted about 20 seconds.
