Bagana is a large cone, and one of Melanesia’s youngest and most active volcanoes. Bagana erupts a slow moving, blocky lava, in flows which can last for months or even years. It is named after Billy Mitchell, a 20th-century United States Army general who is regarded as the father of the United States Air Force. Bagana emits volcanic gases (including water vapor and sulfur dioxide) almost continuously, and frequently extrudes thick lava flows. Bagana volcano is a large lava cone which may have been formed as recently as 300 years ago. Fresh lava flows cover the slopes of Hawaii’s Kilauea Volcano. We consider the possibility that, as a result of this eruption, the magma supply was diverted from Billy Mitchell to Bagana. 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. It is especially unique since loud, violent eruptions have been recorded at Bagana, yet this is not its primary eruption style. Add your article. Fresh lava flows are difficult to distinguish from the barren rock of Tolbachinsky Dol, a volcanic plateau. Volcanoes have helped shape our planet. Bagana is one of 17 post-Miocene stratovolcanoes on Bougainville. A stop date with "(continuing)" indicates that the eruption was considered to be ongoing as of the date indicated. The volcanic plume and clouds are both white. The fresh lava is dark brown, while lighter brown areas were likely stripped of vegetation by volcanic debris or acidic gases. Land Since then there have been at least 22 eruptions. Image of the Day Home Nature Terrain Volcano Bagana. U.S. General Floyd L. Parks flew over the Solomon Islands on 27 October 1948 and witnessed the eruption of Bagana. One of the most active volcanoes in Papua New Guinea, in eruption since at least early 2000, Bagana is located on the mountainous spine of Bougainville Island. Caption by Robert Simmon. Bagana was discovered (by westerners, at least – presumably the local population was well aware of the volcano but that rarely counts) as an active volcano in the 1840’s, when it was seen erupting from ships. Just a reminder that yesterday was the 30th anniversary of the Redoubt volcanic eruption on April 21, 1990. The present-day cone might only be 300 years old. Data is reported through the last data update (10 December 2020). We consider the possibility that, as a result of this eruption, the magma supply was diverted from Billy Mitchell to Bagana. Older lava flows are covered in light green vegetation, and the surrounding forests are dark green. A small lava dome occurs on the north side of the volcano. (2012, March 9). The volcano was continuously erupting between 2000 and 2015, and then again in 2016. In 1937, an eruption from Bagana was heard in Kieta, around 50 km away.

The volcano emits gases (including water vapor and sulfur dioxide) almost continuously, and frequently spits up thick lava flows. These eruptions were predominantly andesitic lava flows from the summit crater, although occasional pyroclastic flows occur. Photo courtesy of Jack Lockwood, U.S. Geological Survey. The first recorded eruption of Bagana was in 1842, and eruptions since then have been recorded, even during the Pacific War (1940s). Fresh lava flows radiate from Kilauea’s Pu’su ’O’o, crater, as the Volcano’s longstanding eruption continues. It features a 1750-m-high lava cone constructed by an accumulation of viscous andesitic lava flows. The Weekly Volcanic Activity Report is a cooperative project between the Smithsonian's Global Volcanism Program and the US Geological Survey's Volcano Hazards Program. What caused Bagana to form and what kind of damage did it do? Space Shuttle photo STS61A-0467-0009 Bagana is one of seven active volcanoes on Papua New Guinea’s Bougainville Island.

Bagana volcano, occupying a remote portion of central Bougainville Island, is one of Melanesia's youngest and most active volcanoes. First synoptic analysis of volcanic degassing in Papua New Guinea. It is the most active volcano in the country and located a remote area of central Bougainville Island. Major eruptions occurred in 1950, 1952, and 1966. Bagana is an interesting case. Some explosive eruptions produce nuee ardentes and voluminous ash clouds. 2008 earthquake A magnitude 6.2 earthquake occurred 38 km SW of Bagana volcano on Tuesday 23 December 2008. Despite its enormous emissions of gas, the typical activity of the volcano is a sluggish effusion of lava flows in eruptions lasting months at a time. Billy Mitchell is a volcano in the central part of the island of Bougainville, just north-east of the Bagana Volcano in Papua New Guinea. Bagana volcano contains a sparsely vegetated symmetrical cone, built up mostly of andesitic lava flows. NASA images By Jesse Allen and Robert Simmon using EO-1 ALI data. Imagery from Landsat 7 shows that the flow was established some time between March 2011 and February 2012.
