A STUDY OF RECENT VERTICAL CRUSTAL ACTIVITIES IN
TIANJIN AREA
First Crust Monitoring and Application Center,CEA,Tianjin 300180
Abstract The vertical deformation rates in Tianjin area was calculated from standard data of repetition measurement during 20052012,and the interference of settlement of each line was excluded to enhance the information of crustal movement. The recent motion of block and recent activity of fault were studied based on the results in the area. The results showed that the overall trend of vertical deformation were to rise at northern part and to fall at southern part in Tianjin. There were differences in movement of the blocks. Some tilted, some overall rose, and some pleated. The recent activity rate of main faults in Tianjin Area was in 0.251.16 mm/a.Most of faults activity were inverse, and a few normal.
Key words ：
Tianjin area
vertical deformation rates
block motion
fault activity
land subsidence
