The Analysis of Recent Deformation Characteristics in Jiangsu
Abstract We collect and calculate the GPS continuous station data, regional station data and leveling data of the Jiangsu area between 2011 and 2015. The characteristics of horizontal deformation in this area are researched by using the time series of GPS baseline and the strain rates. The fitting method considering annual and semi-annual periods is adopted to calculate the velocity of the Maoshan fault vertical deformation. We analyze the vertical deformation of this area. The results show that Jiangsu is controlled by the stress field extrusion of the crust and that the main strain direction in most areas is east-west. The Jiangsu section of the Tanlu fault zone is located in the north-south gradient with tension and extrusion. The vertical velocity of this area is normal. The horizontal and vertical results show that Maoshan fault is the tension fault.
Key words :
Tanlu fault zone
