Gunung Hibok-Hibok

The 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, the high point of the island, has a youthful morphology with summit and flank lava domes, one of which partially fills a crater breached to the NW. 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, Hibok-Hibok (also known as Catarman), lies at the NW end of the island ~6 km NW of Mt. Mambajao. This andesitic-to-rhyolitic volcano contains several lava domes, including Mt. Vulcan on its NW flank. Major eruptions from Hibok-Hibok during 1871-75 and 1948-53 formed flank lava domes and produced pyroclastic flows that devastated coastal villages.
