Several landslides occur every year in the world, causing great damage to infrastructure and loss of life. Detection and monitoring of landslides is very important for implementing appropriate mitigation measure to reduce the loss of life and damage to property. Iran is prone to huge landslides due to its special continental conditions, topographic and tectonic situation and climate conditions. In this investigation, we use the technique of Interferometry Synthetic Aperture Radar (InSAR) to detect and monitor landslides in Taleghan region. The results are obtained from processing of 23 ASAR images acquired in the region by the Envisat satellite. We show evidence for several creeping landslides and obtain their deformation history between 2003 and 2009 via InSAR time-series analysis. We also report on our field investigation that we did to check the results of InSAR analysis.
