| Abstract: | We obtain a unified horizontal velocity field of continental China and vicinity through measurements at 81 GPS stations provided by the National Key Infrastructure Project, Crustal Movement Observation Network of China. The velocity field delineates patterns of movements and deformation of active crustal blocks in continental China under the Eurasia-fixed reference frame. The space-based geodesy also clearly shows for the first time the horizontal movement and deformation of continental China induced by indentation of the Indian plate. The data provide kinematic constraints for simulating dynamic process of continental lithospheric deformation. |
