Abstract The relation between horizontal crust movement and the gravity change was studied and it is simulated that the spacial gravity change caused by the horizontal displacement of a crustal cuboid in a single direction is distributed in a negative symmetry.Being taken as an example, the distribution of the gravity change in the western China caused by the horizontal crustal movement and combining with the GPS velocity field and DEM data was calculated,and then the results were compared with the gravity changes by satellite gravimetry and an explanation was given.
Key words :
satellite gravity
gravity change
crustal horizontal displacement
China’s west region
velocity field
