| Abstract | ||
| One of the hazards that has occurred in many regions in recent years is landslide hazards. Identifying areas prone to landslides and estimating their rates plays an important role in managing and controlling this hazard. Radar interferometry is an efficient method for measuring ground surface displacement. This technology allows continuous monitoring of small ground surface movements with high accuracy and over a wide range. This technology has become very popular in the study of natural ground hazards, including landslides, subsidence, earthquakes, and volcanic activity. This technique compares the phase taken from two radar data sets at two different times and, by creating an interferogram, is able to measure changes in the ground surface over time. In this study, Sentinel 1 radar images from 2016 and 2024 were used to estimate and identify the amplitude movements. And the SARSCAPE software was used to process the information. During the study period, the maximum amount of slope material displacement was 34 cm, indicating that the region is active in terms of slope movements. The results of this study showed that radar images have good potential for detecting slope instability and calculating their displacement. | ||
