Sulawesi lies within the complex zone of interaction between the Australian, Pacific, Philippine and Sunda Plates in which many small microplates have developed.

Are tectonic plates?
Tectonic plates are pieces of Earth’s crust and uppermost mantle, together referred to as the lithosphere. The plates are around 100 km (62 mi) thick and consist of two principal types of material: oceanic crust (also called sima from silicon and magnesium) and continental crust (sial from silicon and aluminium).
Why Indonesia has the most active volcanoes?
The geography of Indonesia is dominated by volcanoes that are formed due to subduction zones between the Eurasian plate and the Indo-Australian plate. The latter group is in one volcanic arc together with the Philippine volcanoes. The most active volcano is Mount Merapi on Java.
What type of volcanoes are in Indonesia?
Most volcanoes in Indonesia consist of stratovolcanoes, but this does not mean that the resulting eruptions are always explosive and they have a long period.
