Study of Disaster Information Extraction using C/L-Band SAR Interferometry

The object of this study is to consider the ground surface displacements that occurred due to the movement of Philippine sea plate movements in the adjacent area of Huatung Valley in eastern Taiwan. We have first performed differential SAR interferometry (D-InSAR) to clarify crustal deformation activity and estimated the displacement values by comparing GPS measurements to evaluate. According to the results by ENVISAT/ASAR interferometry. The calculated displacement values ranged between -1.4 cm and +1.4 cm, which coincide on the active fault area. It was clearly appeared that the northern part of Hualien city seem to sunk approximate 20 mm along to the slant range direction. We have also completed to generate L-band ALOS/PALSAR interferograms successfully: some topographic. It is expect to acquire and more detail processing of. Finally, we plan compare with GPS displacements at the hazardous areas.
