Abstract In this paper,we use the displacement time series for a period between 2 and 6 years after the 2011 Kunlun mountain MS8.1 earthquake.The deformation field is simulated by post-seismic viscoelastic relaxation,then we use the semi analytic plane delamination model to analyze the lithospheric rheological structure of northern Kunlun.The lower crust and upper mantle's viscoelastic flow mainly causes post-seismic relaxation.Models of viscoelastic stress relaxation in a Maxwell half-space gives a best fitting result.The best thickness of elastic upper crust is 15 km-20 km,the Moho depth is 70 km, the valid viscosity of lower crust ranges from 1×1019 Pas to 2.5×1019 Pas and the viscosity of the upper mantle ranges from 1×1019 Pas to 6.3×1019 Pas.The result is consistent with the inversion of post-seismic viscoelastic relaxation caused by Manyi earthquake,thus it can provide significant basis for understanding tectonic movement in the Qinghai-Tibet plateau.
