چکیده انگلیسی
Surface temperature and surface temperature anomaly calculations yield a heat flux between 14.4 and 35.5Â W/m2 at the western crater and between 7.72 and 28.3Â W/m2 at the eastern crater. These values are well-correlated with other known low-level activity volcanoes. The annual and long term consistency of the thermal pattern is investigated. The location and extent of surficial hydrothermal alteration within and surrounding the Tendürek craters is identified by band ratioing and indexing using ASTER visible through shortwave infrared bands. Spectral identification of gypsum, hydroxides, sulfates, hydrated sulfates and clay mineralisation indicates pervasive acid-sulfate alteration due to the activity of fumarole vents around Tendürek craters.
