The lava flows from Bagana are andesitic in composition (intermediate composition) and are considered the biggest volcanic hazard that Bagana produces. Kiwi expert Dr Ian Schipper has just returned from an expedition to Papua New Guinea's remote and unstable Bagana volcano, which is leaking toxic volcanic gases. Bagana is a massive symmetrical, roughly 1750-m-high lava cone largely constructed by an accumulation of viscous andesitic lava flows. The first known eruption of Bagana was in 1842. Bagana volcano is a massive, symmetrical, roughly 1750-m-high cone built largely by rapid accumulation of viscous andesitic lava flows. But every once in awhile there is just a hot spot in lava just flows out of Bagana. Bagana is part of a family of silicic volcanoes. Figure above: Devastated area from another Papua New Guinea volcano, Goropu. The reason Bagana is interesting, and can be used to better understand the volcanics in Papua New Guinea, is that eruptions at Bagana have been monitored for some time. Eruptions at the volcano usually consist of lava flows and occasional pyroclastic flows. Some explosive eruptions produce nuee ardentes and voluminous ash clouds. Cinder Cone: Bagana is a Cinder Cone type of volcano located in Pap New Guinea on the Solomon Sea Plate which is part of a group of very small plates on the south end of the Pacific plate. Pyroclastic deposits are a minor volume of the volcano. Rising to 1750m above the Papua New Guinea island of Bougainville – or roughly the same height as Mt Hikurangi on New Zealand’s East Coast – Bagana is one of Melanesia’s youngest and most active volcanoes. Bagana Volcano [4] Bagana Volcano (06°09′S; 155°11′E) sits on Bougainville island where the Solomon Sea Plate subducts beneath the Pacific Plate . The entire edifice could have been constructed in about 300 years at its present rate of lava production. Just northeast of Bagana, one of 17 volcanoes on Bougainville, is the volcano crater lake, Billy Mitchell. Figures above: Bagana eruptions from space (Images from NASA), VW is a higher education, k-12, and public outreach project of the. This is in addition to numerous eruptions throughout the 20th century. If they were fluid, they would form gentle, long slopes (as seen at Hawaiian volcanoes).

Time-line showing four main types of volcanic activity at Bagana Volcano from 1943 to 2017 (legend top left). Quite a number of active volcanoes are located in relatively remote areas, but their activity is being reported more often now because of satellite imagery. Bagana volcano, occupying a remote portion of central Bougainville Island, is one of Melanesia’s youngest and most active volcanoes. Located on the mountainous spine of Bouganville Island, it is both far from any cities or large towns and hard to reach due to the rough terrain. The volcano could be a part of a lot of things-it could be there due to subduction, or spreading. When the new website was launched in May 2013 following three years of database conversion and restructuring, this catalog of Holocene volcanoes and eruptions was renamed "Volcanoes of the World" with an initial version of 4.0, in recognition of the three previous editions of the book published by Smithsonian scientists (in 1981, … These lava flows are thick, and although they may not travel as fall as fluid lava flows, they can travel far enough, completely covering everything in its path. Major eruptions occurred in 1950, 1952, and 1966. One such active volcano is Bagana. The exceptions to this include Kīlauea (in Hawai`i, USA) and similar volcanoes where fluid lavas can travel far. Just north-east of Bagana is the volcano crater lake Billy Mitchell. Location of major volcanoes on Bougainville Island. Lava bursts followed at intervals of 5-10 minutes.

Volcano Type: Cinder Cone. In addition to these thick lava flows, Bagana also produces pyroclastic flows, however, in comparison, the volume of pyroclastic material is minimum to the amount of lava produced. Bagana is an active volcano located in the centre of the island of Bougainville, Papua New Guinea, the largest island of the Solomon group. Located in Hawaii Volcanoes National Park, it is an elongated dome built of lava eruptions from a central crater and from lines of craters extending along east and southwest rifts, or fissures.
