摘要

After the May 12, 2008 M_s 8 Wenchuan earthquake, the authors extract the high-precision deformation data covering the whole quake-stricken area (～500 km×350 km) by using SAR Interferometry approach (InSAR), which provides important information for the earthquake mechanism research. By analyzing InSAR imaging geometry and the characteristics of ALOS PALSAR data, the authors get some qualitative knowledge of the Wenchuan earthquake. This work provides helpful information for the related research and a basis for the quantitative inversion of the earthquake rupture.
