Details for: Tangkoko-Duasudara

The 1149-m-high elongated Tongkoko volcano, seen in this composite photo from the south, rises above Bitung city and is the NE-most volcano on the island of Sulawesi. The summit of the volcano, which is elongated in a NW-SE direction, contains a large crater with a central cone. Historical eruptions have occurred since 1680 from both the summit and an east flank vent, Batu Angus. Tongkoko volcano and its neighbor Dua Saudara are the most prominent features of Gunung Dua Saudara National Park, a noted wildlife preserve. Photo by A.R. Sumailani, 1973 (Volcanological Survey of Indonesia).
