| Abstract | In this study we analysed 55 RADARSAT 1 InSAR images acquired from August 2006-July 2010 to monitor deformation of permafrost slopes along the Mackenzie Valley Pipeline Corridor. Results from two corner
reflectors installed near a landslide show a 10 and 20 cm motion from 2006-2010. Our InSAR measurement also shows that the lower steeper slope is moving faster than upper slope. This differential motion may be due to a combination of thaw depth,
slope angle and ground moisture. |
