The Iyang-Argapura volcanic complex is across the lowlands about 50 km WNW from Raung volcano. Several Holocene volcanic cones are present, and valleys up to 1,000 m deep dissect the heavily eroded basal Iyang volcano. Fumaroles occur in some of the many explosion pits found in the summit crater complex.
