| Abstract: | With the homogeneous elastic strain block model and the horizontal crustal movement velocity field obtained by GPS measurements, the movement parameters and strain parameters of the northeastern margin of the Qinghai-Tibet block are calculated. The uniform deformation of the blocks, and the relative boundary motion between the adjacent blocks including strike slip and extrusion rate are calculated from the each block movement parameters and strain parameters. Combining with the tectonic characteristics and GPS velocity profile locating at Haiyuan-Liupan Arc, the present day tectonic activity are discussed. |
| Keywords: | elastic block strain model GPS velocity Qinghai-Tibet block |
