Deformation Monitoring Around Salt Lake in Qinghai-Tibet Plateau Using Time-Series InSAR with Sentinel-1A Images from 2014–2018
2019
Since 2011, The area of the Salt Lake was increasing due to the bursting of the Zonag Lake burst. The expansion of the lake would accelerate the melting of permafrost, leading to more severe surface deformation around the lake. In this paper, the deformation of permafrost area around the Salt Lake have been retrieved applying time-series InSAR method with Sentinel-1A data from 2014. 12 to 2018.12. The preliminary result shows that obvious deformation has been observed around the Salt Lake, with the maximum deformation rate larger than −20 mm/year. Future work will focus on analyzing the relationship between the deformation pattern and the area extend of the Salt Lake.
