Abstract

Abstract: Radar satellites combined with InSAR technology have been widely used in the field of high-precision surface deformation monitoring. In this paper, Sentinel-1A single look complex images, before and after the Jiuzhaigou M_s7.0 earthquake are chosen to derive the seismic deformation field using the D-InSAR method. The results show that the northwest side of the epicenter displays a relatively uniform subsidence. In the subsidence funnel area, the maximum settlement is 25.1 cm in the line of sight direction. While in the southeast side of the epicenter, the broken surface shows an uneven uplift, and the maximum lifting amount is 11.6 cm. The research shows that based on Sentinel-1A data, the D-InSAR technology can provide a fast and effective means for the quantitative analysis of seismic deformation field. It can provide necessary information for explaining the earthquake mechanism and assessing the disaster situation. There would be broad application prospects in the field of surface deformation survey in the future.

Key words: Sentinel-1A, D-InSAR, surface deformation, Jiuzhaigou, earthquake
