Beijing: A 6.5-magnitude earthquake rattled southwest China late on Tuesday, killing at least five people, with up to 100 feared dead, according to a government estimate.
Five people died and more than 60 were injured in the quake, the official Xinhua news agency said, including 30 who were in critical condition.
But China's National Commission for Disaster Reduction estimated that as many as 100 people may have perished, based on 2010 census data of the mountainous, sparsely populated region.
Over 130,000 houses may be damaged, it added in a statement posted on its website, based on a preliminary analysis of the disaster in a remote region of
Sichuan province.
The quake occurred around 9.20 pm local time, not far from the site of a massive 8.0-magnitude earthquake that struck in 2008 leaving 87,000 people dead or missing.
Its epicentre was 284 kilometres north of the provincial capital Chengdu and struck at a depth of 10 kilometres, the US Geological Survey said.
The affected region, Jiuzhaigou county, includes one of the country's most famous national parks, a UNESCO World Heritage Site known for karst formations and lakes.
At least one tourist was killed and four others injured in the park, the state-run People's Daily newspaper said, with more than 100 other people trapped there.
