Abstract :
On May 12th, 2008, a destructive earthquake of magnitude 8.0 struck Wenchuan. The seismic region is located at the transition zone between Qinghai-Tibet Plateau and the Sichuan Basin, which has a complex geological tectonic background. In this paper, we intend to investigate the Wenchuan earthquake using the Differential Interferometric SAR(D-InSAR) technique. Due to the large scale of the crustal deformation affected by the disastrous earthquake, SCANSAR images show more advantages than conventional strip-map mode images. And taking account the vegetation conditions, the L band images are suitable than the C band images for our study. Therefore, we choose to use ALOS SCANSAR interferometric observations to obtain a preliminary co-seismic displacement filed of the Wenchuan earthquake.
