| Summary: | Indonesia is one of the countries located between the ring of fire. The ring of fire is a zone where there is a lot of seismic activity that is formed due to the meeting of tectonic plates. Indonesia itself is in area where 3 large tectonic plates meet. This led to the creation of volcanic arcs in Indonesia which consisted of volcanic ranges. This geographical condition causes Indonesia's territory to be potentially and vulnerable to the danger of volcanic eruptions. In the past few years, many active volcanoes in Indonesia have shown high volcanic activity and are prone to disasters. In this research, an analysis of the characteristics and thermal anomalies of each volcano that represents each volcanic arc was carried out. Thermal anomalies can be detected from the temporal surface temperature obtained by processing Visible Near Infrared and Thermal Infrared ASTER images using the Land Surface Temperature algorithm. The thermal characteristics of each volcanoes can be used to detect possible future eruptions. The results showed that Karangetang volcano and Gamalama volcano which respectively represent the Sulwesi-Sangihe Arc and the Halmahera Arc have the same typical characteristics, namely showing a high significant thermal change just before the eruption. Meanwhile, Tangkuban Perahu volcano, which represents the Sunda arc, does not show a striking temperature anomaly before the eruption. So do the Banda Api volcano which represents the Banda Arc where its surface temperature fluctuations from time to time tend to be flat and it has indeed been recorded that it has never experienced an eruption in the past 10 years.
