The Banda Sea is one of Indonesia’s deepest oceans, at the most more than 6.500 m deep. It spans a large area, all the way to Sulawesi in the west. At the center of the sea south of Seram there are a small group of ten islands plus some uninhabited small corral islands, called the Banda Islands. The most important are Banda Besar, Neira and Gunung Api (“the mountain of fire”). All of the islands are of volcanic origin.
