Oblate, 20-km-long Camiguin Island just off the coast of north-central Mindanao Island consists of four overlapping stratovolcanoes overlying older buried edifices. Mt. Mambajao forms the high point of Camiguin Island at 1552 m. It has a youthful morphology with summit and flank lava domes, one of which partially fills a crater breached to the NW, but has not had historical eruptions. The eroded stratovolcanoes of Mt. Butay and Mt. Ginsiliban form the SE tip of the island and lie at one end of the NNW-SSE trending line of vents cutting across the island. The Binone cinder cone lies along the SE coast. The youngest volcano, and the only historically active one, is Hibok-Hibok (also known as Catarman). It lies at the NW end of the island, about 6 km NW of Mt. Mambajao. This andesitic-to-rhyolitic volcano contains several lava domes, including Mt. Vulcan on its NW flank. Major eruptions during 1871-75 and 1948-53 formed flank lava domes at Hibok-Hibok and produced pyroclastic flows that devastated coastal villages.
