Tore (volcano)
Tore is a volcano located in the northern part of the island of Bougainville Island, Bougainville, Papua New Guinea. Violent Pleistocene eruptions produced two ignimbrite fans stretching west to the coast, and a 6 km by 9 km caldera. A post-caldera lava cone on the caldera's southern rim is the source of lava flows. Well-preserved features suggests a recent date for this cone and a nearby ash cone.

Mount Balbi
Mount Balbi is a Holocene stratovolcano located in the northern portion of the island of Bougainville Island, Bougainville, Papua New Guinea. A gentle prominence at is the highest point of the island. There are five volcanic craters east of the summit, one of which contains a Volcanic crater lake, crater lake. The summit is composed of coalesced cones and lava domes which host a largsolfaterafield. There are numerous fumaroles near the craters, though Balbi has not erupted in historic time.

Bougainville Province
Bougainville ( ; ; Tok Pisin: ''Bogenvil''), officially the Autonomous Region of Bougainville (Tok Pisin: ''Otonomos Region bilong Bogenvil''), is an autonomous region in Papua New Guinea. The largest island is Bougainville Island, while the region also includes Buka Island and a number of outlying islands and atolls. The interim capital is Buka, although this is considered temporary, with the capital likely to move. One potential location is Arawa, the previous capital. In 2011, the region had an estimated population of 250,000 people. The lingua franca of Bougainville is Tok Pisin, while a variety of Austronesian and non-Austronesian languages are also spoken. The region includes several Polynesian outliers where Polynesian languages are spoken. Geographically the islands of Bougainville and Buka are part of the Solomon Islands archipelago, but are politically separate from the independent country of Solomon Islands. Historically the region was known as the North Solomons. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Papua New Guinea
Papua New Guinea (abbreviated PNG; , ; tpi, Papua Niugini; ho, Papua Niu Gini), officially the Independent State of Papua New Guinea ( tpi, Independen Stet bilong Papua Niugini; ho, Independen Stet bilong Papua Niu Gini), is a country in Oceania that comprises the eastern half of the island of New Guinea and its offshore islands in Melanesia (a region of the southwestern Pacific Ocean north of Australia). Its capital, located along its southeastern coast, is Port Moresby. The country is the world's third largest island country, with an area of . At the national level, after being ruled by three external powers since 1884, including nearly 60 years of Australian administration starting during World War I, Papua New Guinea established its sovereignty in 1975. It became an independent Commonwealth realm in 1975 with Elizabeth II as its queen. It also became a member of the Commonwealth of Nations in its own right. There are 839 known languages of Papua New Guinea, one of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Lava Cone
Lava is molten or partially molten rock (magma) that has been expelled from the interior of a terrestrial planet (such as Earth) or a moon onto its surface. Lava may be erupted at a volcano or through a fracture in the crust, on land or underwater, usually at temperatures from . The volcanic rock resulting from subsequent cooling is also often called ''lava''. A lava flow is an outpouring of lava during an effusive eruption. (An explosive eruption, by contrast, produces a mixture of volcanic ash and other fragments called tephra, not lava flows.) The viscosity of most lava is about that of ketchup, roughly 10,000 to 100,000 times that of water. Even so, lava can flow great distances before cooling causes it to solidify, because lava exposed to air quickly develops a solid crust that insulates the remaining liquid lava, helping to keep it hot and inviscid enough to continue flowing. The word ''lava'' comes from Italian and is probably derived from the Latin word ''labes'', w ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcano
A volcano is a rupture in the crust of a planetary-mass object, such as Earth, that allows hot lava, volcanic ash, and gases to escape from a magma chamber below the surface. On Earth, volcanoes are most often found where tectonic plates are diverging or converging, and most are found underwater. For example, a mid-ocean ridge, such as the Mid-Atlantic Ridge, has volcanoes caused by divergent tectonic plates whereas the Pacific Ring of Fire has volcanoes caused by convergent tectonic plates. Volcanoes can also form where there is stretching and thinning of the crust's plates, such as in the East African Rift and the Wells Gray-Clearwater volcanic field and Rio Grande rift in North America. Volcanism away from plate boundaries has been postulated to arise from upwelling diapirs from the core–mantle boundary, deep in the Earth. This results in hotspot volcanism, of which the Hawaiian hotspot is an example. Volcanoes are usually not created where two tectonic plates slide ...

Bougainville Island
Bougainville Island (Tok Pisin: ''Bogenvil'') is the main island of the Autonomous Region of Bougainville, which is part of Papua New Guinea. It was previously the main landmass in the German Empire-associated North Solomons. Its land area is . The population of the whole province, including nearby islets such as the Carterets, is approximately 300,000 (2019 census). The highest point is Mount Balbi, on the main island, at . The much smaller Buka Island, , lies to the north, across the wide Buka Strait. Even though the strait is narrow, there is no bridge across it, but there is a regular ferry service between the key settlements on either side. The main airport (or airstrip) in the north is in the town of Buka. Bougainville is the largest island in the Solomon Islands archipelago. Most of the islands in this archipelago (which are primarily concentrated in the southern and eastern portions of it) are part of the politically independent Solomon Islands. Two of these islands ...

Mountains Of Papua New Guinea
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable terrain and ...
