Land deformation modelling of Taiwan earthquake using interferometry technique

Abstract

A strong earthquake with M 6.4 in 14 km shallow depth occurs in the Eastern of Taiwan. To clarify the land deformation model and area damage covered, the SAR data of Sentinel-1A/B in ascending and descending orbit extracted. The data is collected from coseismic and post-seismic. In processing SAR data, Differential Interferometry Synthetic Aperture Radar (D-InSAR) technique applied. The result presents significant deformation reach to 250 millimeters in line of sight (LOS) for ascending and descending orbit.
