Analisis Spasial Potensi Kerawanan Gerakan Tanah Berdasarkan Integrasi Koreksi Radiometrik Sensor Termal Landsat 8 Pada Periode Tahun 2013 Di daerah Desa Gunung Masigit

The study area is an area with significant limestone mining activities. Mining activities can change the slope to become steep, potentially causing land movement. This research aims to determine the factors influencing the potential vulnerability of land movement and to determine changes in the potential vulnerability of land movement in the research area in the period of 2013 and 2023 using the Overlay and weighting method based on Geographic Information Systems (GIS). In addition, the research was also conducted as an initial step in mitigating against land movement disasters. The parameters used in this study include rainfall, slope, land cover, lithology, soil type and distance to active faults. The results showed that the potential vulnerability of land movement is influenced by rainfall, slope, lithology, land cover, soil type and distance to active faults. The factors of rainfall, slope, and lithology have a major influence on vulnerability of land movement. The research analysis resulted in three levels of potential vulnerability of land movement, namely low vulnerability, medium vulnerability, and high vulnerability with an area of 10.21%, 84.98%, and 4.8% respectively in 2013, while in 2023 it has an area of 20.11%, 78.83%, 1.05% respectively. The results showed that the potential for high vulnerability of land movement in 2023 decreased compared to 2013. This is due to the significantly decreased rainfall intensity and strong lithological conditions
