Geothermal energy moves to the surface of the earth through the fractures and porosityin the rocks and appears as hot springs, geysers, and the volcano vapors. Non-renewable energy sources are limited and expiring. Geothermal, wind, etc are appropriate alternatives for these resources. This study was performed with the aim of identifying geothermal resources in the Taftan volcano region using Landsat 8 images. Surface temperatures, rock units, faults, iron oxide zones, and hydrothermal alterations were determined. After weighing each layer, geothermal potential map of the area was prepared by fuzzy logic method. The results showed that the geothermal potential in the eastern part of the region corresponds to the travertine and the study area is geothermaly active. Geothermal potentials also showed good agreement with faults, hydrothermal alteration and igneous rocks.
