The first step in inventorying geothermal areas is identifying geothermal area through describing the surface thermal features, then measuring the physical properties (temperature, pH, conductivity, etc) and analyzing the water samples to cluster the type of surface thermal features and supported by the regional geology. Based on the literature data and surface thermal features, Southeast Sulawesi has 15 geothermal areas and numerous active geothermal manifestations there. Geologically, Southeast Sulawesi is associated with a non-volcanic environment with metamorphic and sedimentary rocks mostly. The inventory data was conducted in 2011 and identifying the active geothermal surface features at Puriala, Parora, Toreo, and Laonti Hot Springs. The Parora, Toreo, and Laonti Hot Springs are located near the southeast coastal of Sulawesi, while Puriala hot springs is a little bit far from the coastal area. These hot springs have temperature of 33-50.6oC at air temperature of 27.5oC, neutral pH, manifested at low terrain on altitude of 11-25 m above sea level, the Parora which manifested very near to the coastal line has the higher electrical conductivity of 2,650 µS/cm, while Puriala, Toreo, dan Laonti has lower electrical conductivity of 382-1,256 µS/cm, clearly color, salty, air bubbles, H2S odour, chloride type and mostly plotted on partial equlibrium zone of Na-K-Mg relative diagram. Based on the regional geological map of Lembar Lasusua-Kendari, Sulawesi. It is in the Meluhu Formation which consists of Sandstone, quartzite, black shale, red shale, phyllite, slate, limestone and siltstone, which aged Trias-Jura. This paper only discusses the early data inventory of geothermal surface features at geothermal areas of these hot springs, in order to be used for the geothermal society.
