| Abstract: | The co-seismic displacement of Yushu earthquake occurred on April 14th,2010 is achieved by D-InSAR using ALOS PALSAR data.For the orbit error of PALSAR,the least squares adjustment technique is firstly used to remove the error ramp.At last,the results of co-seismic displacement interferogram and the profile show that the most serious destroyed area is located 20~30km southeast from the epicenter.The surface rupture is about 30km.The northeast plate of causative fault displaces uplift while the southwest pla... |
