Abstract

Land movement or mass wasting is a geomorphic process, where the process is a natural process of weathering, erosion and deposition that causes material changes on the earth's surface and landscape. This can be described as the potential for bedrock, to move downslope. Due to the lack of basic information and limitations of survey methods, this research was carried out to provide information about land movements. The research is a follow-up study based on the results of geological mapping, where the research area has several points where land movement is located. Remote Sensing Technology and Geographic Information Systems (GIS) are powerful tools for monitoring landslides and assessing their danger. Land movements in the research area can be tracked based on what occurs yearly. This effort to reach the ground surface was carried out as steps in mitigating and investigating unexpected natural disasters. Based on these things, this research seeks to produce problem-solving using a geographic information system approach to reaching surface points in the 2018–2022 period so that it is helps solve surface characteristics that occur. This research has a problem limitation that focuses on surface cooling in the research area. The method used in this research is DInSAR (Differential Interferometry Synthetic Aperture Radar). This method can provide information about earth’s surface changes using other electromagnetic wave phases recorded at two different observation times. Next, an analysis of the relationship between surface settlement and factors influencing changes occurring in the research area is carried out, to obtain mitigation against unexpected natural disasters. The research was conducted in 4 sub-districts in Bogor Regency, West Java Province, namely Rumpin, Cigudeg, Leuwiliang and Cibungbulang sub-districts with an area of 81 km². Based on the stratigraphic sequence of the research area, from old to young formations, it consists of the Bojongmanik Formation (Tmb) with a Middle Miocene age, the Tuff, and Breccia Formation (Tmtb) with a Late Miocene age, and Volcano Breccia (Qvb) with a Pleistocene age.
