The earthquake hit the Baiyu County in Tibetan Autonomous Prefecture of Garze at 8:42 pm, said China Earthquake Networks Center.
There have been no reports of casualties, as the epicentre is located in a remote region where traffic is backward and telephone communication is unavailable, state-run Xinhua reported quoting local government officials.
However, some buildings of local residents surrounding the epicentre were damaged in the quake, the report said.
