| Abstract: | InSAR (Synthetic Aperture Radar Interferometry) can only obtain the displacements along direction of LOS (line of sight), it is not the real three-dimensional surface deformation. Therefore it is difficult to analyze both vertical and horizontal terrain displacements. A method combining GPS and InSAR data to calculate three dimensional terrain displacements of Wenchuan earthquake is proposed. The results show that the earthquake pupture is obviously right-leteral and thrust. |
