The approximate location of the 20 September 2013 Qinghai Province Earthquake. Google Maps.
Qinghai Province lies on the northeast of the Tibetan Plateau, a vast upland created by the impact of India and Eurasia; the 32 highest mountains in the world are on the Plateau (the 33rd, Tirich Mir, is in the nearby Hindu Kush, Afghanistan). India is still moving northwards, but Eurasia is unable to do the same, resulting in an unusual degree of folding and uplift. This has resulted in a number of faults running east-west across the plateau, with sections being forced eastward into China.
