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 ...

Bagana
Bagana is an active volcanic cone located in the centre of the island of Bougainville, Papua New Guinea, the largest island of the Solomon group. It is the most active volcano in the country, occupying a remote portion of central Bougainville Island. It is one of Melanesia's youngest and most active volcanoes. Bagana is a massive symmetrical, roughly 1855-m-high lava cone largely constructed by an accumulation of viscous andesitic lava flows. The entire lava cone could have been constructed in about 300 years at its present rate of lava production. Eruptive activity at Bagana is frequent and is characterized by non-explosive effusion of viscous lava that maintains a small lava dome in the summit crater, although explosive activity occasionally producing pyroclastic flows also occurs. Lava flows form dramatic, freshly preserved tongue-shaped lobes up to 50 m thick with prominent levees that descend the volcano's flanks on all sides. Just north-east of Bagana is the volcan ...

Garbuna Group
The Garbuna Group of volcanoes consists of three volcanic peaks, Krummel, Garbuna, and Welcker, atop a shield volcano. They are located at the southern end of the Willaumez Peninsula, just to the west of the town of Kimbe, in West New Britain, Papua New Guinea. Garbuna contains a large thermal field, probably Papua New Guinea's largest. Until recently, it was assumed that the Garbuna volcano was probably dormant, or perhaps extinct. The last eruption was believed to have occurred around 1300 AD, or 700 years ago. Evidence from past eruptions indicates large amounts of tephra and lava were produced. However, on 17 October 2005 the Garbuna volcano erupted without warning. Ash was reported 4,000 m above the summit. An ash warning for aircraft was distributed by the Darwin office of the Australian Bureau of Meteorology on 19 October, by which time a second new vent had appeared. Ash was apparently drifting to the north-west on 19 October and had contaminated some village wat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Dakataua (volcano)
The Dakataua Caldera is located at the northern tip of the Willaumez Peninsula, New Britain, Papua New Guinea. The peninsula includes the 350 m high andesitic Mount Makalia stratovolcano. The last major collapse of Dakataua was during the Holocene around 800 CE. The most recent eruption on the caldera's rim was Mount Makalia in 1890, producing lava flows and cinder cones. Caldera lake Dakataua caldera lake is about 76 m above sea level, has total surface area , and the maximum depth approximately 120 m. It is horseshoe shaped, roughly bisected by a peninsula. It is a freshwater lake that is alkaline with a pH of up to 8.2. It is presumed to be formed by rainwater gradually filling in the caldera. While the lake supports various kinds of life, it does not support any species of fish. Migo the Lake Monster There is a folk legend that a monster called the migo (or masali) inhabits the lake. In 1993 a Japanese film crew led by Tetsuo Nagata captured what they claimed to be t ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Bola (volcano)
The Bola volcano, also known as Wangore, is an andesitic stratovolcano, located south-west of the Dakataua caldera. It is tall and has a wide summit crater. The most recent lava flow was erupted from the summit crater and flowed to the west. This viscous flow is at least 50 m thick, thus leaving an irregularity in the profile of the volcano. The unforested summit crater and weak fumarolic activity suggest that the most recent eruption may have been only a few hundred years ago.

Goodenough Island
Goodenough Island in the Solomon Sea, also known as Nidula Island, is the westernmost of the three large islands of the D'Entrecasteaux Islands in Milne Bay Province of Papua New Guinea. It lies to the east of mainland New Guinea and southwest of the Trobriand Islands. It is roughly circular in shape, measuring with an area of and a shoreline of . From a coastal belt varying in width from in width, the island rises sharply to the summit of Mount Vineuo, above sea level, making it one of the most precipitous islands in the world. The small outlier Wagifa Island lies to the south-east of the island, and is included within Goodenough's administration. Climate and vegetation Like much of New Guinea, the climate is tropical with high temperatures and humidity throughout the year. The northwest monsoon season lasts from December to March and brings sudden rain squalls. From May to October southeasterly winds are cooler and more gentle. Tropical cyclones are infrequent.

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.
