| description | The Daguangbao landslide is located in the Gaochuan village, Anxian county in the Sichuan province, China.It is the largest coseismic landslide triggered by the Ms 8.0 Wenchuan earthquake on May 12，2008 and it caused enormous human casualties and property damage.The time series InSAR technique is utilized to retrieve the deformation characteristics of the landslide to monitor the displacement and disasters warning.In order to get the deformation and deformation rate, eleven scenes of radar images collected from Radarsat-2 satellite between 2014 and 2015 and one pair of TanDEM bi-static images are used to obtain the time series values in the study.The study shows that the landslide is in a state of dynamic balance during the observation period, and its tiny deformation is induced by precipitation and earthquakes happened around the landslide.Therefore the landslide will not cause big geological disasters. |
