| Abstract: | According to the principles of D-InSAR,by using Doris and ENVISAT SAR data,two-pass method of D-InSAR is utilized to acquire coseismic surface deformation images caused by L'Aquila(Italy)earthquake.Preliminary quantitative cognition was completed based on the D-InSAR interferogram.The results show that the main driving force of the earthquake is the southwest wards and up back-arc spreading of the area and the earthquake makes the area uplift 25.2 cm in the sight line direction of SAR. |
