Fault Mapping in Weh Island based on Fault Fracture Density Method (FFD)

Abstract: Pulau Weh merupakan pulau vulkanik yang dilalui jalur sesar aktif the Great Sumatran Fault. Keberadaan jalur sesar aktif pada suatu kawasan berimplikasi pada ancaman bahaya gempa bumi. Kami telah menggunakan data Digital Elevation Model (DEM) dari Shuttle Radar Topography Mission (SRTM) untuk pemetaan jalur-jalur sesar di Pulau Weh. Data DEM yang diproduksi oleh SRTM diekstrak menjadi hillshade dengan memberikan variasi sudut penyinaran matahari dan altitude 45o. Analisis topografi permukaan bumi memberikan pe… Show more

“…The analysis results are in the form of a lineament density map. This method produces lineaments that are related to the structure and reflection of topographic features such as the straightness of rivers, valleys, faults and fractures, as well as the emergence of geothermal manifestations [23]. The parameters of lineament density, land surface temperature, and vegetation density are overlaid to map the geothermal heat of the Gedongsongo area.…”

“…data DEM diekstraksi menjadi hillshade dengan memberikan sudut penyinaran matahari sebesar 0°, 45°, 90°, 135°, 180°, 225°, 270°, dan 315° dan ketinggian 45°. Hal ini dilakukan untuk memvisualisasikan semua lereng dan mendapatkan bayangan matahari yang sama (Yanis et al, 2019).…”

“…In this research, geomorphological observations will be carried out using digital topographic data DEM (Digital Elevation Model), which is related to fault estimation, to see the structure's condition at the fault junction in Mount Semeru. DEM (Digital Elevation Model) research conducted by explains that DEM can be used to obtain information about geological structures by extracting shaded relief, lineament, slope, aspect, drainage network, and curvature information (Mahbub & Ragil, 2021;Putra et al, 2023;Raharja et al, 2020;Yanis et al, 2019).…”
