摘要

On October 6^th, 2016, there was an earthquake happened in the southeast of Taiwan. To understand the impact of the earthquake, differential interferometry synthetic aperture radar (DInSAR) such as Small Baseline Subset (SBAS) InSAR approaches is applied to extract the surface movement caused by earthquake using time-series Sentinel-1A images. DInSAR has been widely used to detect and monitor surface deformation with dependable precision. Many natural disasters happened in Taiwan, and many studies are related to these events. This study used Sentinel-1A images and GMTSAR to implement the SBAS for the analysis of surface deformation. The preliminary results show that the earthquake caused slightly uplift deformation in the study area.
