Determination of mass movements in slow-motion landslides by the Cosi-Corr method

Landslides bring damage to urbanization and cause negative effects on the quality of agricultural and forest areas and rivers. Therefore, it is of vital importance to detect displacements in landslide areas causing the loss of life and property. Different measurement methods such as Global Navigation Satellite System (GNSS) measurements, remote sensing etc. are used for monitoring movements in landslide areas and revealing surface deformations. Co-Registration of Optically Sensed Images and Correlation (Cosi-Corr) method (Remote sensing method) is one of these methods. Although the Cosi-Corr method is used commonly to determine the displacements in dune, glacier, and earthquake areas, there are very few studies related to its use in landslide areas. In this study, the mass movements occurring in the study area were determined by the Cosi-Corr method and the use of very high resolution optical satellite images. General geomorphologic evaluations were performed related to the mass movements in the study area. Consequently, this study shows to be applicable of the Cosi-Corr method in determining the mass movements associated with slow-motion landslides.
