Fonuafoʻou
Fonuafo‘ou ("New land" in Tongan), formerly known as Falcon Island, is a submarine volcano in the western part of the Ha'apai group in Tonga. The volcano has created an island several times throughout history. It was first spotted by the crew of the British ship HMS ''Falcon'' in 1867, while it was still a coral reef. On 11 October 1885, the volcano erupted and spouted tons of molten lava 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 un .... Three days later, on 14 October 1885, the eruption created an island, which was named Falcon island by the British. Several eruptions occurred in 1894, 1921, 1927, 1928, 1933 and 1936, consolidating the island and expanding its surface (6 km in diameter, in height in 1949). In 1949, another eruption caused the explosion and the coll ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Falcon Island
Falcon Island is one of the islands in the Palm Islands group, off the eastern coast of Queensland, Australia. The nearest island is Esk Island. The Nyawaygi name of the island is ''Carbooroo''. Along with nine of the other islands within the Palm Islands group, it falls under the local government area of the Aboriginal Shire of Palm Island. The island was gazetted as an Aboriginal reserve on 20 September 1941, along with neighbouring small islands, with the intention of extending Palm Island Aboriginal Settlement Palm Island Aboriginal Settlement, later officially known as Director of Native Affairs Office, Palm Island and also known as Palm Island Aboriginal Reserve, Palm Island mission and Palm Island Dormitory, was an Aboriginal reserve and penal set ..., but it was never used as such.

Submarine Volcano
Submarine volcanoes are underwater vents or fissures in the Earth's surface from which magma can erupt. Many submarine volcanoes are located near areas of tectonic plate formation, known as mid-ocean ridges. The volcanoes at mid-ocean ridges alone are estimated to account for 75% of the magma output on Earth.Martin R. Speight, Peter A. Henderson, "Marine Ecology: Concepts and Applications", John Wiley & Sons, 2013. . Although most submarine volcanoes are located in the depths of seas and oceans, some also exist in shallow water, and these can discharge material into the atmosphere during an eruption. The total number of submarine volcanoes is estimated to be over 1 million (most are now extinct) of which some 75,000 rise more than 1 km above the seabed. Only 119 submarine volcanoes in Earth's oceans and seas are known to have erupted during the last 11,700 years. Hydrothermal vents, sites of abundant biological activity, are commonly found near submarine volcanoes. Effe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tongan Language
Tongan (English pronunciation: or ; ') is an Austronesian language of the Polynesian branch native to the island nation of Tonga. It has around 187,000 speakers. It uses the word order verb–subject–object. Related languages Tongan is one of the multiple languages in the Polynesian branch of the Austronesian languages, along with Hawaiian, Māori, Samoan and Tahitian, for example. Together with Niuean, it forms the Tongic subgroup of Polynesian. Tongan is unusual among Polynesian languages in that it has a so-called ''definitive accent''. As with all Polynesian languages, Tongan has adapted the phonological system of proto-Polynesian. # Tongan has retained the original proto-Polynesian *h, but has merged it with the original *s as . (The found in modern Tongan derives from *t before high front vowels). Most Polynesian languages have lost the original proto-Polynesian glottal stop ; however, it has been retained in Tongan and a few other languages including Rapa Nui ...

Haʻapai
Haʻapai is a group of islands, islets, reefs, and shoals in the central part of Tonga. It has a combined land area of . The Tongatapu island group lies to its south, and the Vavaʻu group lies to its north. Seventeen of the Haʻapai islands are inhabited. Their combined population is 5,419. The highest point in the Ha‘apai group, and in all of Tonga, is on Kao, which rises almost above sea level. The administrative capital village of Haʻapai District is Pangai, which is located on Lifuka. Geography Haʻapai comprises 51 islands that lie directly west of the Tonga Trench. They constitute a chain of both volcanic and coral islands, including Kao, the highest point in the kingdom, which stands high. Farther to the east are the coral islands, which are inhabited. The Haʻapai archipelago lies north of Tongatapu and south of Vavaʻu. Seventeen of the islands are inhabited, including the main islands of Lifuka and Foa.

Tonga
Tonga (, ; ), officially the Kingdom of Tonga ( to, Puleʻanga Fakatuʻi ʻo Tonga), is a Polynesian country and archipelago. The country has 171 islands – of which 45 are inhabited. Its total surface area is about , scattered over in the southern Pacific Ocean. As of 2021, according to Johnson's Tribune, Tonga has a population of 104,494, 70% of whom reside on the main island, Tongatapu. The country stretches approximately north-south. It is surrounded by Fiji and Wallis and Futuna (France) to the northwest; Samoa to the northeast; New Caledonia (France) and Vanuatu to the west; Niue (the nearest foreign territory) to the east; and Kermadec (New Zealand) to the southwest. Tonga is about from New Zealand's North Island. First inhabited roughly 2,500 years ago by the Lapita civilization, Tonga's Polynesian settlers gradually evolved a distinct and strong ethnic identity, language, and culture as the Tongan people.

Coral Reef
A coral reef is an underwater ecosystem characterized by reef-building corals. Reefs are formed of colonies of coral polyps held together by calcium carbonate. Most coral reefs are built from stony corals, whose polyps cluster in groups. Coral belongs to the class Anthozoa in the animal phylum Cnidaria, which includes sea anemones and jellyfish. Unlike sea anemones, corals secrete hard carbonate exoskeletons that support and protect the coral. Most reefs grow best in warm, shallow, clear, sunny and agitated water. Coral reefs first appeared 485 million years ago, at the dawn of the Early Ordovician, displacing the microbial and sponge reefs of the Cambrian. Sometimes called ''rainforests of the sea'', shallow coral reefs form some of Earth's most diverse ecosystems. They occupy less than 0.1% of the world's ocean area, about half the area of France, yet they provide a home for at least 25% of all marine species, including fish, mollusks, worms, crustaceans, echinoderms, sp ...

Lava
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 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcanoes Of Tonga
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 p ...
