| Abstract | There are many difficulties to create details geological map in an active volcano. The main difficulty comes from hard terrain condition to be reached which is related to the higher cost of field activity. To solve this problem, Landsat 8 imageries as an optical sensor were used in this study. The objective of this study focussed on recognizing geology of the area that will be used for geothermal exploration. The methodology in this study is analyses and interpretation of Landsat 8 image, and also applied the remote sensing technique under torrid zones. Mt. Lamongan was chosen as study site, which is a young volcano from Mt. Tarub that located in the east. The results showed the geomorphology delineation of Mt. Lamongan indicates geological fault in NW-SE direction and there are many fractures beneath the surface, which is related with geothermal reservoir. High temperature zone in TIR (Thermal Infrared Radiometer) band located in the northern part of the area is associated with thermal activities, caused by existence of manifestations. The manifestations of the geothermal in the Mt. Lamongan is located in the surface near the fault system. Based on the analysis of the geomorphology and brightness temperature, Mt. Lamongan is an area that has geothermal potential. It was detected by using Landsat 8 imageries analyses. This study can be used for future development by geological, geophysics and geochemistry study to delineate area of the subsurface reservoir. |
