Monte Hibok-Hibok

Camiguin

Stratovulcano · Philippines · 1552 m

Mt. Vulcan (left) and Hibok-Hibok (right) are two historically active lava domes on Camiguin Island. These two domes were active in the 19th and 20th centuries, with Mt. Vulcan forming in 1871. Several historical eruptions have occurred at Hibok-Hibok with the most recent during 1948-1953, when pyroclastic flows devastated island villages. The 20-km-long Camiguin Island lies just off the coast of north-central Mindanao Island and consists of four overlapping volcanoes and flank lava domes.

Sintesi geologica

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.
