Large amounts of strike-slip motion are accommodated through major faults and their splays along the plateau, such as the Altyn Tagh Fault, Kunlun Fault, Haiyuan Fault and Xianshuihe fault systems. Left-lateral strike-slip motion squeezes the crustal blocks of the Tibetan Plateau outwards, forcing it to move eastwards. Meanwhile, the strike-slip motion also results in east-west extension of the plateau, causing normal faults to break within the thickened crust.[5][6]
