Camiguin Mindanao
Camiguin Mindanao is a potentially active volcanic group within the Philippines.
Location
The Camiguin Mindanao Group, including Hibok-Hibok one of the active volcanoes in the Philippines, forms the volcanic island province of Camiguin, located 8 km north of central Mindanao, in the region of Northern Mindanao.
Physical Features
Camiguin Mindanao is about 20 kilometres (12 mi) long by 15 kilometres (9.3 mi) wide with a number of volcanoes, pyroclastic cones and craters.
The highest point in the island is the active volcano Hibok-Hibok at the northwestern end of the island, with an elevation of 1,332 metres (4,370 ft) above mean sea level (asl), and a base diameter of 10 kilometres (6.2 mi).
The other volcanos in the group are all potentially active volcanos because of their close proximity to Hibok-Hibok. Mount Vulcan is 671 m asl, on the northwestern flank of Hibok-Hibok. Mount Mambajao is located in the centre of Camiguin. Mount Ginsiliban is 581 m asl, at the southern end of Camiguin. Mount Uhay is located north of Mount Ginsiliban.
Its Domes and cones are Campana Hill, Minokol Hill, Tres Marias Hill, Mount Carling, Mount Tibane, and Piyakong Hill.
Hot springs, craters and a maar are close to Hibok-Hibok.
Solfataric activity has been a precursor to eruptions.
Volcanic Activity
The most recent eruption was in the period 1948 to 1953. During this period, Hibok-Hibok formed flank lava domes and produced pyroclastic flows that devastated coastal villages.
The Camiguin Mindanao group is permanently monitored for volcanic and seismic activity.
Geology
The rock type is predominantly andesite and rhyolite.
Camiguin is the northern terminus of the Central Mindanao Arc.
All volcanoes in the Philippines are part of the Pacific ring of fire.
