Abstract On the basis of vertical deformation rate and the activities rate of main fault zone which calculated from leveling data during 2000-2008, the vertical movement character of crustal blocks and the activity of main fault zone in BeijingTianjinTangshan area were studied. There was a rising vertical deformation in the north and a declining one in the south of BeijingTianjinTangshan area in past ten years. These vertical deformation roughly matched the topography and the landform, it reflected that the tectonic activities was a kind of inheritable movement. Most of the blocks had tilting activities.The activities of main fault were different, some of them were normal faulting activities, some of them were reverse faulting activities, some of them were turn twitching activities at vertical plane.The vertical activity rate of fault zone in BeijingTianjinTangshan area were between 1.00-2.00 mm/a.
Key words ：
