In a study of geothermal prospects, the first thing to do is identify the geological condition in the area. This study aims to determine the geological conditions in area of "TG14" geothermal field using remote sensing method on ASTER and DEM imagery and the impact to land surface temperature. The land surface temperature (LST) from thermal infra red (TIR) band using a retrieval method. Surface emissivity was determined based on Normalized Difference Vegetation Index (NDVI) of study area. Remote sensing analysis is good approach to identification of geological structure from surface that control thermal manifestation in "TG14" geothermal field. The hottest temperature in the area along the deep-seated Great Sumatera Fault and the western graben transform fault. Heated by magma assosiated with the volcanic deposits. Its show the Great Sumatera Fault is the main structure in geothermal field which assosiated with high LST and thermal manifestation.
