Abstract

In long-term slow ground deformation monitoring, conventional InSAR technology is affected by factors of temporal decoherence, spatial decoherence and atmospheric effects. In order to overcome these limitations, this paper uses two InSAR time series analysis of permanent scatters and small baseline subset methods to analyze ground deformation caused by fault movement. Based on principles, 34 scenes ENVISAT-ASAR data covered the Dangxiong area were processed in this paper. The results show that, southern fault of Nyenchen Tanglha (northwest margin of Yangbajing-Dangxiong basin) presents a trend of ground uplift. Flat area in the middle of Yangbajing-Dangxiong basin presents a trend of ground subsidence. The front fault of Tanggula Mountain (southeast margin of Yangbajing-Dangxiong basin) presents a trend of ground subsidence. These results were accordance with fault movement in situ. When fault moving, high-level areas were pushed to uplift, while the low-lying areas were squeezed to subsidence. This demonstrates that InSAR time series analysis of permanent scatters and small baseline subset methods are reliable in fault movement monitoring. The fault activity can be analyzed based on monitoring results. This will provide data for earthquake prediction.
