The volcanic belt is one of the largest subduction-zone related volcanic provinces in the world, stretching some 3,200 kilometres (2,000 mi) and comprising about 2 million km of volcanic and plutonic material. The volcanism within the volcanic belt was related to the subduction of the ancient Kula Plate , which moved in
