Districts Of Rotuma
Rotuma is a Fijian dependency, consisting of Rotuma Island and nearby islets. The island group is home to a large and unique Polynesian indigenous ethnic group which constitutes a recognisable minority within the population of Fiji, known as "Rotumans". Its population at the 2017 census was 1,594, although many more Rotumans live on mainland Fijian islands, totaling 10,000. Geography and geology The Rotuma group of volcanic islands are located (Suva to Ahau) north of Fiji. Rotuma Island itself is long and wide, with a land area of approximately , making it the 12th-largest of the Fiji islands. The island is bisected by an isthmus into a larger eastern part and a western peninsula. The isthmus is low and narrow, only wide, and is the site of Motusa village ( Itutiu district). North of the isthmus is Maka Bay, and in the south is Hapmafau Bay. There is a large population of coral reefs in these bays, and there are boat passages through them.

Fiji
Fiji ( , ,; fj, Viti, ; Fiji Hindi: फ़िजी, ''Fijī''), officially the Republic of Fiji, is an island country in Melanesia, part of Oceania in the South Pacific Ocean. It lies about north-northeast of New Zealand. Fiji consists of an archipelago of more than 330 islands—of which about 110 are permanently inhabited—and more than 500 islets, amounting to a total land area of about . The most outlying island group is Ono-i-Lau. About 87% of the total population of live on the two major islands, Viti Levu and Vanua Levu. About three-quarters of Fijians live on Viti Levu's coasts: either in the capital city of Suva; or in smaller urban centres such as Nadi—where tourism is the major local industry; or in Lautoka, where the Sugarcane, sugar-cane industry is dominant. The interior of Viti Levu is sparsely inhabited because of its terrain. The majority of Fiji's islands were formed by Volcano, volcanic activity starting around 150 million years ago. Some geo ...

Suva
Suva () is the capital and largest city of Fiji. It is the home of the country's largest metropolitan area and serves as its major port. The city is located on the southeast coast of the island of Viti Levu, in Rewa Province, Central Division. In 1877, the capital of Fiji was moved to Suva from Levuka, the main European colonial settlement at the time, due to its restrictive geography and environs. The administration of the colony was transferred from Levuka to Suva in 1882. As of the 2017 census, the city of Suva had a population of 93,970, and Suva's metropolitan area, which includes its independent suburbs, had a population of 185,913. The combined urban population of Suva and the towns of Lami, Nasinu, and Nausori that border it was around 330,000: over a third of the nation's population. (This urban complex, excluding Lami, is also known as the Suva-Nausori corridor.) Suva is the political, economic, and cultural centre of Fiji. It is also the economic and cultural ...

Solkope
Solkope is a small and densely wooded island off the southern coast of Rotuma in the Fiji Islands, at the edge of the fringing coral reef. It is separated from the main island of Rotuma by a channel that is between 50 and 200 m wide, and lies immediately southeast of the village of Kalvaka in the district of Noatau. It 765 m long east–west, and up to 515 m wide, and rises to a height of 128 m. Its area is 0.3 km2. From the sea, it cannot be recognised as a separate island. Secessionist movement In 2000 Solkope was the subject of a land ownership dispute, as a consequence of an attempted secession of Rotuma from Fiji which was jointly orchestrated by the Molmahao Clan of Noatau district, and unrecognized micronation Dominion of Melchizedek. According to documents tendered in court pertaining to the case, the native landowner of Solkope Island, Hiagi Apao and Melchizedek's "Head of House of Elders", Tzemach "Ben" David Netzer Korem, concluded a "99 year sovereign master lea ...

Solnohu
Solnohu or Sol Nohu, also known as Solnoho, Solnahu and Solnahou, is a small crescent-shaped uninhabited island in the Rotuma Group of Fiji. The island is of special importance in Rotuman and Tongan funerary customs. Geography Solnohu is the fourth largest island in the Rotuma Group of sixteen volcanic islands located 646 kilometres (401 mi) north of Fiji. It has an area of 9.6 hectares and lies approximately 70 meters away from the southern district of Juju on the main island of Rotuma, but it is still within the fringing reef. The island is also one of two outliers to the south of Rotuma, the other being Solkope. Climate The climate in the area is temperate. The average annual temperature is 20 °C. The warmest month is March, when the average temperature is 26 °C, and the coldest is December, with 0 °C. The average annual rainfall is 3,420 millimeters. The wettest month is February, with an average of 504 mm of precipitation, and the driest is Sept ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Hawaiite
Hawaiite is an olivine basalt with a composition between alkali basalt and mugearite. It was first used as a name for some lavas found on the island of Hawaii. It occurs during the later stages of volcanic activity on oceanic islands such as Hawaii, which happens to be when the alkaline metals are most present. In gemology, hawaiite is a colloquial term for Hawaii-originated peridot, which is a gem-quality form of the mineral olivine. Description Hawaiite is an aphanitic (fine-grained) volcanic rock produced by rapid cooling of lava moderately poor in silica and enriched in alkali metal oxides (potassium oxide plus sodium oxide). It is often impractical to determine the mineral composition of such a fine-grained rock, and so hawaiite is defined chemically. Under the TAS classification, hawaiite is sodic trachybasalt, with a silica content close to 49 wt%, a total alkali metal oxide content close to 6%, and wt% > wt% + 2. This places hawaiite in the S1 field of the TAS dia ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Basalt
Basalt (; ) is an aphanite, aphanitic (fine-grained) extrusive igneous rock formed from the rapid cooling of low-viscosity lava rich in magnesium and iron (mafic lava) exposed at or very near the planetary surface, surface of a terrestrial planet, rocky planet or natural satellite, moon. More than 90% of all volcanic rock on Earth is basalt. Rapid-cooling, fine-grained basalt is chemically equivalent to slow-cooling, coarse-grained gabbro. The eruption of basalt lava is observed by geologists at about 20 volcanoes per year. Basalt is also an important rock type on other planetary bodies in the Solar System. For example, the bulk of the plains of volcanism on Venus, Venus, which cover ~80% of the surface, are basaltic; the lunar mare, lunar maria are plains of flood-basaltic lava flows; and basalt is a common rock on the surface of Mars. Molten basalt lava has a low viscosity due to its relatively low silica content (between 45% and 52%), resulting in rapidly moving lava flo ...

Shield Volcano
A shield volcano is a type of volcano named for its low profile, resembling a warrior's shield lying on the ground. It is formed by the eruption of highly fluid (low viscosity) lava, which travels farther and forms thinner flows than the more viscous lava erupted from a stratovolcano. Repeated eruptions result in the steady accumulation of broad sheets of lava, building up the shield volcano's distinctive form. Shield volcanoes are found wherever fluid low-silica lava reaches the surface of a rocky planet. However, they are most characteristic of ocean island volcanism associated with hot spots or with continental rift volcanism. They include the largest volcanoes on earth, such as Tamu Massif and Mauna Loa. Giant shield volcanoes are found on other planets of the Solar System, including Olympus Mons on Mars and Sapas Mons on Venus. Etymology The term 'shield volcano' is taken from the German term ''Schildvulkan'', coined by the Austrian geologist Eduard Suess in 1888 an ...

Coral
Corals are marine invertebrates within the class Anthozoa of the phylum Cnidaria. They typically form compact colonies of many identical individual polyps. Coral species include the important reef builders that inhabit tropical oceans and secrete calcium carbonate to form a hard skeleton. A coral "group" is a colony of very many genetically identical polyps. Each polyp is a sac-like animal typically only a few millimeters in diameter and a few centimeters in height. A set of tentacles surround a central mouth opening. Each polyp excretes an exoskeleton near the base. Over many generations, the colony thus creates a skeleton characteristic of the species which can measure up to several meters in size. Individual colonies grow by asexual reproduction of polyps. Corals also breed sexually by spawning: polyps of the same species release gametes simultaneously overnight, often around a full moon. Fertilized eggs form planulae, a mobile early form of the coral polyp which, when m ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
