Özet

Tendtirek volcano is a polygenetic, basaltic shield volcano formed by successive alkaline basalt flows. It is one of the youngest volcanoes of Turkey; both historical and Holocene activities have been reported for the volcano. Continuous hydrothermal and fumarole activity has been observed on the twin summit craters located 4.5 km apart. ASTER daytime and nighttime satellite imagery acquired between 2001 and 2014 are used to calculate surface temperature, surface temperature anomaly and relative radiative heat flux from the craters to determine a base value for the current thermal emission.
