Abstract

Landslide is one of the natural hazards in which monitoring the displacements and changes requires the use of special techniques due to its slow, continuous and gradual movements. In this regard, the PSI technique with extensive terrestrial coverage as well as high temporal and spatial resolution, is one of the most accurate and low-cost remote sensing techniques to identify and display displacements. Since the village of Mashayekh in the city of Mamasani in Fars has been facing the problem of Landslides for several years, and this phenomenon has caused the gradual destruction of the houses and farms of the villagers, so, this research tries to evaluate and monitor the displacement of the Landslide mass using the mentioned technique. For this purpose, 75 radar images of Sentinel 1 were selected during 3 periods from 2014 to 2019 and were processed by PSI method. Based on the obtained results, the maximum Displacement Rate at the Landslide mass from October 2, 2014 to May 31, 2016 at the rate of 1. 5 cm per year, during the period of July 18, 2016 to December 28, 2017 at the rate of 5. 3 cm per year. And during the period from January 9, 2018 to July 27, 2019, it has reached 5. 7 centimeters per year. In addition, the area of Landslide mass has been expanded from 3. 5 Km2 to 4 Km2. The results of the research indicate a continuous and progressive displacement in this mass in the study area.
