The Oto volcanic group consists of five stratovolcanoes and a caldera of early to late Pleistocene age. The oldest volcanoes, Ko and Husa, are about 800-900,000 years old, and the steep-sided Oto, Mululus and Mateleloch volcanoes range from about 190,000 to less that 70,000 years old (Blake and McDougall 1973, Johnson and Blake 1972). The 4-km-wide Busui caldera of probable Pleistocene age is formed in a broad, low-angle cone of dominantly pyroclastic material. The names of Oto, Mululus and Mateloch peaks on published maps differ from that used by local inhabitants and in the geological literature.
