Local government in northwest China's Qinghai Province has initiated a "Level II" emergency contingency plan after a magnitude-7.4 earthquake jolted its Maduo County of Golog Tibetan Autonomous Prefecture. 

The tremor was felt strongly by residents in the provincial capital city of Xining, which is 385 kilometers away from the county seat of Maduo.

So far there have been no reports of casualties and housing collapses, and no impact to the power grid or communication networks, local authorities stated.

Sections of highways and bridges have collapsed in the quake-hit area, blocking the passage of vehicles, according to Xinhua.
