Tefala (Vanuatu)
Tefala (Ile Tevala, Téfala, Île Tévala) is a small uninhabited island in the Pacific Ocean, belonging to the Shefa Province of Vanuatu. Geography The island lies 2.6 km north-west of the small island of Laika (island), Laika, 9.4 km north of the island of Tongoa, and east of Epi (island), Epi. Geology Tefala and other small islands scattered around Tongoa (Laika (island), Laika, Sail Rock) were once a part of a larger landmass formed by the eruptions of the submarine volcano of Kuwae in the second half of the 15th century. The volcanic arc, called the New Hebrides arc, is home to a number of more famous volcanoes, such as Mount Yasur, Yasur, Gaua, and Ambrym.

Pacific Ocean
The Pacific Ocean is the largest and deepest of Earth's five oceanic divisions. It extends from the Arctic Ocean in the north to the Southern Ocean (or, depending on definition, to Antarctica) in the south, and is bounded by the continents of Asia and Oceania in the west and the Americas in the east. At in area (as defined with a southern Antarctic border), this largest division of the World Ocean—and, in turn, the hydrosphere—covers about 46% of Earth's water surface and about 32% of its total surface area, larger than Earth's entire land area combined .Pacific Ocean .

Vanuatu
Vanuatu ( or ; ), officially the Republic of Vanuatu (french: link=no, République de Vanuatu; bi, Ripablik blong Vanuatu), is an island country located in the South Pacific Ocean. The archipelago, which is of volcanic origin, is east of northern Australia, northeast of New Caledonia, east of New Guinea, southeast of the Solomon Islands, and west of Fiji. Vanuatu was first inhabited by Melanesian people. The first Europeans to visit the islands were a Spanish expedition led by Portuguese navigator Fernandes de Queirós, who arrived on the largest island, Espíritu Santo, in 1606. Queirós claimed the archipelago for Spain, as part of the colonial Spanish East Indies, and named it . In the 1880s, France and the United Kingdom claimed parts of the archipelago, and in 1906, they agreed on a framework for jointly managing the archipelago as the New Hebrides through an Anglo-French condominium. An independence movement arose in the 1970s, and the Republic of Vanuatu was fou ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Shefa Province
Shefa is one of the six provinces of Vanuatu, located in the center of the country and including the islands of Epi and Efate and the Shepherd Islands. The province's name is derived from the initial letters of SHepherd and EFAte. It has a population of 78,723 people and an area of 1,455 km2. Its capital is Port Vila, which is also the capital of the nation. History In the 1860s, Havanna Harbour, north Efate, was the centre of development in Shefa, with cotton plantations the focus. With dwindling prices for cotton, agricultural administrators turned to maize and coffee, before settling mainly with coconuts and cattle which are the main agricultural products today. The French and British continued to have conflicting interests in Vanuatu (then known as New Hebrides) and decided upon a Joint Naval Commission, or Condominium, in 1887, with the Joint Court opened in 1910, it is still used today. Shefa Province was a strategic location during World War II for the mainly Americ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Laika (island)
Laika (also Ile Laika, Laïka, Île Laïka) is a small uninhabited island in the Pacific Ocean, a part of the Shepherd Islands archipelago in the Shefa Province of Vanuatu.

Tongoa
Tongoa Island is an inhabited island in Shefa Province of Vanuatu in the Pacific Ocean. Geography Tongoa is the largest island of Shepherd Islands archipelago. The island is heavily vegetated and shows geothermal activity. Tongoa is of recent volcanic origin but currently has no currently active volcano. There are numerous volcanic cones on the island and some black sand beaches. The estimated terrain elevation above the sea level is some 191 metres. There is an airport on the island – Tongoa Airport (TGH). Flora and fauna The interior part of the island is dense rain forest. The island is named after the Tongoa plant which grows in the area. Megapodes nest on the island. The only non-human mammals on the island are the Vanuatu flying fox and Tonga leather, or insular flying fox.

Kuwae
Kuwae was a landmass that existed in the vicinity of Tongoa and was destroyed by volcanic eruption in fifteenth century, probably through caldera subsidence. The exact location of the caldera is debated. A submarine caldera, now known as Kuwae caldera that is located between the Epi and Tongoa islands is a potential candidate. Kuwae Caldera cuts through the flank of the Tavani Ruru volcano on Epi and the northwestern end of Tongoa. Another potential candidate is a proposed caldera between Tongoa and Tongariki. The submarine volcano Karua, one of the most active volcanoes of Vanuatu, is near the northern rim of Kuwae Caldera. Caldera location and Kuwae landmass In Tongoan folklore, Kuwae is a lost land in the vicinity of Tongoa and was destroyed by a massive volcanic eruption, probably associated with caldera subsidence. In the legend of ''Ti Tongoa Liseiriki'', the young man in Tongoa escaped the eruption along the coast of Kuwae to Tongariki which became a remnant of submerg ...

Volcanic Arc
A volcanic arc (also known as a magmatic arc) is a belt of volcanoes formed above a subducting oceanic tectonic plate, with the belt arranged in an arc shape as seen from above. Volcanic arcs typically parallel an oceanic trench, with the arc located further from the subducting plate than the trench. The oceanic plate is saturated with water, mostly in the form of hydrous minerals such as micas, amphiboles, and serpentine minerals. As the oceanic plate is subducted, it is subjected to increasing pressure and temperature with increasing depth. The heat and pressure break down the hydrous minerals in the plate, releasing water into the overlying mantle. Volatiles such as water drastically lower the melting point of the mantle, causing some of the mantle to melt and form magma at depth under the overriding plate. The magma ascends to form an arc of volcanoes parallel to the subduction zone. Volcanic arcs are distinct from volcanic chains formed over hotspots in the middle of a te ...

Mount Yasur
Mount Yasur is a volcano on Tanna Island, Vanuatu, high above sea level, on the coast near Sulphur Bay, northeast of the taller Mount Tukosmera, which was active in the Pleistocene. It has a largely unvegetated pyroclastic cone with a nearly circular summit crater 400 m in diameter. It is a stratovolcano, caused by the eastward-moving Indo-Australian Plate being subducted under the westward-moving Pacific Plate. It has been erupting nearly continuously for several hundred years, although it can usually be approached safely. Its eruptions, which often occur several times an hour, are classified as Strombolian or Vulcanian. A large lava plain creeps across the valley at the base. The glow of the volcano was apparently what attracted Captain James Cook on the first European journey to the island in 1774. Today, the mountain is a sacred area for the John Frum cargo cult. Members of the cult revere John Frum, a deified messenger who foretold the bringing of wealth to the isl ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gaua
Gaua (formerly known as ''Santa Maria Island'') is the largest and second most populous of the Banks Islands in Torba Province in northern Vanuatu. It covers 342 km². History Gaua was first sighted by Europeans during the Spanish expedition of Pedro Fernández de Quirós, from 25 to 29 April 1606. The island’s name was then charted as ''Santa María''. Geography Gaua is subject to frequent earthquakes and cyclones. The climate is humid tropical; the average annual rainfall exceeds 3500 mm. It has rugged terrain, reaching up to Mount Gharat (797 m), the peak of the active stratovolcano which lies at the center of the island. Its most recent eruption was in 2013. The volcano has a 6 × 9 km caldera, within which lies a crater lake, known as Lake Letas, which is the largest lake in Vanuatu. To the east of the lake is Siri Waterfall (120 m drop).

Ambrym
Ambrym is a volcanic island in Malampa Province in the archipelago of Vanuatu. Volcanic activity on the island includes lava lakes in two craters near the summit. Etymology Ambrym (also known as ''Ambrin'', ''"ham rim"'' in the Ranon language) was allegedly named by Captain Cook, who is said to have anchored off there in 1774. In fact, his expedition never touched Ambrym. Geography Located near the center of the Vanuatuan archipelago, Ambrym is roughly triangular in shape, about wide. With of surface area, it is the fifth largest island in the country. The summit at the centre of the island is dominated by a desert-like caldera, which covers an area of . With the exception of human settlements, the rest of the island is covered by a dense jungle. Important Bird Area The western part of the island, comprising 17,605 ha of forest, together with gardens around habitation, has been recognised as an Important Bird Area (IBA) by BirdLife International because it supports ...

Wired (magazine)
''Wired'' (stylized as ''WIRED'') is a monthly American magazine, published in print and online editions, that focuses on how emerging technologies affect culture, the economy, and politics. Owned by Condé Nast, it is headquartered in San Francisco, California, and has been in publication since March/April 1993. Several spin-offs have been launched, including '' Wired UK'', ''Wired Italia'', ''Wired Japan'', and ''Wired Germany''. From its beginning, the strongest influence on the magazine's editorial outlook came from founding editor and publisher Louis Rossetto. With founding creative director John Plunkett, Rossetto in 1991 assembled a 12-page prototype, nearly all of whose ideas were realized in the magazine's first several issues. In its earliest colophons, ''Wired'' credited Canadian media theorist Marshall McLuhan as its "patron saint". ''Wired'' went on to chronicle the evolution of digital technology and its impact on society. ''Wired'' quickly became recognized ...
