Data from the Global Volcanism Program of the Smithsonian Institution
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).

The eastern peninsula at the far NE end of Sulawesi near the city of Bitung is occupied by a volcanic complex consisting of two major edifices within a nature reserve. To the north is Tangkoko (also known as Tongkoko), with a large caldera (~3 x 1.5 km) elongated towards the SE from the highest rim point; the rim at the opposite end is more than 400 m lower. Eruptions occurred from the summit crater in the 17th century and in 1801, when the caldera also reportedly contained a cone surrounded by a lake. About 1.5 km down the outer E flank is the Batuangus (or Batu Angus) lava dome, formed in 1801, along with an adjacent vent (Baru Batuangus) that has been the source of all subsequent eruptions. The higher twin-peaked Duasudara (also Dua Suadara) stratovolcano is about 4.5 km SW of the Tangkoko summit. A NE-facing open crater appears to have a hummocky debris flow that reaches the base of the Tangkoko edifice.
