A 7.0 magnitude earthquake has struck a remote, mountainous part of China's southwestern province of Sichuan, killing 19 people, including six tourists, and injuring 247.
The quake hit a sparsely populated area 200 km northwest of the city of Guangyuan late on Tuesday at a depth of 10 km , the US Geological Survey said. It was also close to the Jiuzhaigou nature reserve, a tourist destination.
Sichuan is frequently struck by tremors. A huge quake there in May 2008 killed almost 70,000 people.
A separate quake with a magnitude of 6.6 struck a remote part of China's far northwestern region of Xinjiang, more than 2000 km away, on Wednesday morning, the Chinese earthquake administration said. The People's Daily said 32 people had been injured in the mostly rural area.
The Sichuan government said rescuers were gradually evacuating tourists and residents who had been cut off by landslides.
Six tourists were among those killed, according to the official China News Service.
State television said 19 people had been killed, and that most of those injured were not seriously hurt.
The Sichuan government said that as many as 30,000 tourists had been evacuated from the quake zone, leading to traffic jams on the narrow roads.
A few dozen tourists were camped out at Jiuzhaigou airport, waiting for flights. The airport was open and beginning to evacuate people by air, state media said.
A French man and a Canadian woman suffered light injuries, Xinhua reported.
The Sichuan government said earlier fears that part of a hotel had collapsed were overblown, with only relatively minor damage and everyone evacuated safely.
The Sichuan earthquake administration, which also measured the quake at a magnitude of 7.0, said the epicentre of the tremor was in Ngawa prefecture, which is largely populated by ethnic Tibetans, many of whom are nomadic herders.
The area was rattled by a number of aftershocks on Wednesday.
The Sichuan government said on one of its official social media sites that more than 38,000 tourists were currently visiting Jiuzhaigou.
Shaking was felt in the provincial capital, Chengdu, and as far away as Xian, home of the famous terracotta warrior figures, according to the government.
