An earthquake measuring 6.0 on the Richter scale has struck Sichuan province in China.
The United States Geological Survey says the quake struck on Tuesday evening, 48 kilometres northwest of the city of Guangyuan at a depth of 10km.
No injuries have been reported.
About 70,000 people died when a quake measuring 7.9 struck Sichuan province on 12 May. Since then, more than 12,600 aftershocks have been felt. The China Earthquake Administration says at least seven of them were above 6.0.
The latest quake came a few hours after the Olympic torch was paraded through Sichuan's provincial capital, Chengdu, on the last leg of its journey to Beijing for the opening ceremony.
State news agency Xinhua said the tremors were felt in Chengdu. Huge reconstruction efforts have been under way in the province since the May earthquake left about 5 million people homeless.
