| Abstract: | We simulate GPS horizontal velocity field in terms of rotations of crustal blocks to describe deformation behavior of the Chinese mainland and its neighboring areas.31 crustal blocks are bounded primarily by~30 Quaternary faults with distinct geometries and variable long-term rates of<20 mm/a,and 1 683 GPS velocities were determined from decade-long observations mostly with an averaged uncertainty of 1?2 mm/a.We define GPS velocity at a site by the combination of motion of rigid block and elastic strain ind... |
