Mount Tangkoko

Mount Tangkoko is a stratovolcano in the north of Sulawesi island in Indonesia. Its summit has an elongated deep crater. On the east flank, there is a flat lava dome Batu Angus. Historical records only show eruptions in the nineteenth century.

The Tangkoko Batuangus Nature Reserve is a refuge for such species as the Celebes crested macaque and spectral tarsier.
