Mapping of a Landslide Site with SAR Images in the Taurus Mountains

Remote sensing (RS) techniques help characterize the earth's surface. RS techniques can solve many engineering problems related to natural disasters. Landslides, essential agents of mass wasting and hillslope evolution, are common on mountainous terrains and cause loss of life and property. Interferometric Synthetic Aperture Radar (InSAR) is an effective way to measure land surface altitude changes and map topographic change on earth. Detection of movements in vertical and horizontal directions is needed to evaluate slope failure mechanisms. In this study, we analyzed the landslide after heavy rainfall and created coherence and phase maps with SAR data. We illustrated the potential usage of Sentinel-1 usage in a slow-motion landside site. This study can provide significant geomorphologic information about landslides. Our results show that monitoring landslides with InSAR data where traditional mapping opportunities are missing.
