Abstract.
The geographical scope of the experiment in this paper is Dangxiong in Tibet. The rift basin of Yangbajing-Dangxiong-Gulu locates at the east side of the Nyainqentanglha. The crustal activities in Dangxiong basin are frequent and a great deal of geothermal energy converged under the surface. The geothermic resources were used through the exploitation of underground water. The excessive extraction caused the surface deformation in surrounding areas of the pump wells. In this paper, we investigate the surface deformation caused by the geothermal extraction in Dangxiong with 23 Envisat ASAR images from 2006 to 2010 based on the time series analysis. The results show that the center of the basin was relatively stable. The deformation rate was between -1 mm/yr and 2 mm/yr. The surface subsidence rate of the region with the pump wells was about 8 mm/yr.
