The Sulawesi volcanic arc is a chain of volcanoes located on the island of Sulawesi in Indonesia. This region is part of the larger Pacific Ring of Fire, where tectonic plates converge, leading to volcanic activity. The arc is characterized by several active and dormant volcanoes, which have formed due to the subduction of the Australian Plate beneath the Sundaland Plate. The volcanic arc plays a significant role in the geology and ecology of Sulawesi. The eruptions from these volcanoes contribute to the rich soil, supporting diverse ecosystems. Additionally, the arc influences local climate patterns and is vital for the communities living in the area, providing resources and impacting their livelihoods.
