A 6.6-magnitude earthquake struck southwestern China on Monday, according to the US Geological Survey.
The quake hit around 43 kilometres (26 miles) southeast of the city of Kangding in Sichuan province at a depth of 10 kilometres, the USGS said.
Tremors were felt in the nearby megacity of Chengdu, a resident told AFP.
"I felt it quite strongly," a woman surnamed Chen said. "Some of my neighbours on the ground floor said they felt it very clearly."
Earthquakes are fairly common in China, especially in the country's seismically active southwest.
At least four people were killed and dozens more injured after two earthquakes hit southwestern China in June.
On that occasion, a shallow 6.1-magnitude quake hit a sparsely populated area about 100 kilometres west of Chengdu, the provincial capital of Sichuan with a population of 21 million.
A magnitude 8.0 quake in 2008 in Sichuan's Wenchuan county cost tens of thousands of lives and caused enormous damage.
