Abstract
This Research investigates landslide deformation velocity and time series is using PSI Technique at Kelok 9 area west Sumatra, Indonesia. PSI is an advanced InSAR technique overcoming the problems of temporal and geometrical decorrelation and great precision measurement ground displacement in millimeter. Along Kelok 9 area many times landslide has occurred. In this research 10 ascending Advanced Land Observation Satellite, Phased Array L-band Synthetic Aperture Radar (ALOS PALSAR) images from March 2007 until November 2010 was employed. The processing result was confirmed by doing a ground survey, small drone survey and geological information data on the investigated area. The focus area of the survey was divided into eight areas around the Kelok 9 bridge. The result shows there is significant land movement (land deformation) in eastern and western of Kelok 9 bridge. The average velocity of each area is 59.8-94.3 mm/year and cumulative deformation maximum is 424.8 mm.
