C) GPS Measurements:
Global positioning system (GPS) measurements indicate a total convergence rate of ~38 mm/yr in N21E direction between the Indian and Eurasian plates (Wang et al, 2001). According to the spatial distribution of motions, substantial part of crustal shortening is accommodated within the Tibetan plateau (figure 10). In the north, this deformation seems to be partitioned equally by sinistral strike-slip faults trending nearly orthogonal to the main convergence direction such as the Kunlun fault (figure 11). This eastward motion is accommodated through rotation of material around the eastern syntaxis (figure 10). Especially, this results indicates that the plateau is not only under the effect of rigid block motions towards the east but is also deforming internally while it extrudes eastward.
