AbstractRadar interferometry (InSar) techniques using images from several radar satellites are increasingly being used in slope stability assessment. During the past year there were at least 25 media reports of landslides, some fatal, occurring in various areas in Canada. In this paper, we provide examples of using high resolution (3 m) InSAR techniques from RADARSAT and TerraSAR X to monitor coastal landslide affectiong transportation corridors. The high-resolution InSAR images are very effective in characterizing differential motion within these low velocity coastal landslides. The active wet spring periods are better monitored by the more frequent revisits from TerraSAR X. © Springer-Verlag Berlin Heidelberg 2013.
