Abstract

Cisarua District, situated on the Lembang Fault line, has a high risk due to its proximity to densely populated settlements and its potential for large-magnitude earthquakes. This study aims to analyze the deformation of the Lembang Fault in Cisarua District from 2014 to 2024 using Sentinel-1A and TerraSAR-X imagery data, as well as Digital Terrain Model (DTM) analysis from an Unmanned Aerial Vehicle, employing the high-resolution Differential Interferometric SAR (DInSAR) method. The deformation levels vary from low to high, with a dominance of moderate deformation levels. High deformation was identified on the north and northeast sides, adjacent to the active tectonic zone. The DTM analysis revealed a steep topographic gradient with an elevation of 975.9–1395 masl. The combination of deformation and steep topography indicates a significant risk of landslides. The results of this study are expected to assist in disaster mitigation in the Cisarua District due to the deformation of the Lembang Fault.

Abstract

Aerosols are small particles in the atmosphere that affect the climate through direct and indirect mechanisms. Aerosols can influence the climate and play a role in cloud formation and precipitation. This study aims to analyze the relationship between seasonal changes and aerosol concentrations, and to identify parameters that influence aerosol concentrations in Java Island using remote sensing. The method used in this study is the Pearson correlation test to determine the relationship between seasonal changes and aerosol concentrations in the atmosphere. The results show that there is a relationship between Aerosol Optical Depth (AOD) and rainfall with a correlation value (R) of 0.8. This result indicates a significant relationship between the two variables. Meanwhile, the analysis results between Aerosol Optical Depth (AOD) and wind speed show a correlation value (R) of 0.05. This result indicates that the relationship between Aerosol Optical Depth (AOD) and wind speed is very weak between the two variables.
