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 pla ...

Geographic Coordinates
The geographic coordinate system (GCS) is a spherical or ellipsoidal coordinate system for measuring and communicating positions directly on the Earth as latitude and longitude. It is the simplest, oldest and most widely used of the various spatial reference systems that are in use, and forms the basis for most others. Although latitude and longitude form a coordinate tuple like a cartesian coordinate system, the geographic coordinate system is not cartesian because the measurements are angles and are not on a planar surface. A full GCS specification, such as those listed in the EPSG and ISO 19111 standards, also includes a choice of geodetic datum (including an Earth ellipsoid), as different datums will yield different latitude and longitude values for the same location. History The invention of a geographic coordinate system is generally credited to Eratosthenes of Cyrene, who composed his now-lost ''Geography'' at the Library of Alexandria in the 3rd century ...

Bora Bora
Bora Bora (French: ''Bora-Bora''; Tahitian: ''Pora Pora'') is an island group in the Leeward Islands. The Leeward Islands comprise the western part of the Society Islands of French Polynesia, which is an overseas collectivity of the French Republic in the Pacific Ocean. Bora Bora has a total land area of . The main island, located about northwest of Papeete, is surrounded by a lagoon and a barrier reef. In the center of the island are the remnants of an extinct volcano, rising to two peaks, Mount Pahia and Mount Otemanu; the highest point is at . Bora Bora is part of the Commune of Bora-Bora, which also includes the atoll of Tūpai. The languages spoken in Bora Bora are Tahitian and French. However, due to the high tourism population, many natives of Bora Bora have learned to speak English. Bora Bora is a major international tourist destination, famous for its seaside (and even offshore) luxury resorts. The major settlement, Vaitape, is on the western side of the main ...

Mangareva
Mangareva is the central and largest island of the Gambier Islands in French Polynesia. It is surrounded by smaller islands: Taravai in the southwest, Aukena and Akamaru in the southeast, and islands in the north. Mangareva has a permanent population of 1,239 (2012) and the largest village on the island, Rikitea, is the chief town of the Gambier Islands. The island is approximately long and, at , it comprises about 56% of the land area of the whole Gambier group. Mangareva has a high central ridge which runs the length of the island. The highest point in the Gambiers is Mount Duff, on Mangareva, rising to along the island's south coast. The island has a large lagoon in diameter containing reefs whose fish and shellfish helped ancient islanders survive much more successfully than on nearby islands with no reefs. History Mangareva was first settled by Polynesians in the first millennium CE. While carbon dating has so far only dated settlements to 1160-1220, there is evide ...

Mehetia
Meheti'a or Me'eti'a is a volcanic island in the Windward Islands, in the east of the Society Islands in French Polynesia. This island is a very young active stratovolcano east of the Taiarapu Peninsula of Tahiti. It belongs to the Teahiti'a-Mehetia hotspot. The island has an area of and its highest point is 435 metres (1,427 ft). The peak is a well-defined volcanic crater. In 1981 the island was the centre of earthquakes. History Tahitian oral tradition holds that navigators stopped at Mehiti'a, which was regarded as sacred, on their long voyage to New Zealand. This oral history correlates with geological evidence found in southern New Zealand which can be traced back to Mehiti'a. The early Polynesian voyagers commonly gave Polynesian ancestral names and symbolism to new places. The high point of Mehetia is Mount Hiurai (Hi’ura’i/Hikurangi) The name Hikurangi in Aotearoa / New Zealand probably came from Mehetia and the name Hi’ura’i probably has its orig ...

Moua Pihaa
Moua Pihaa is a submarine volcano in French Polynesia. It is located southwest of Mehetia in the Society Islands, and is the largest of a group of seamounts stretching between Mehetia and Tahiti Tahiti (; Tahitian ; ; previously also known as Otaheite) is the largest island of the Windward group of the Society Islands in French Polynesia. It is located in the central part of the Pacific Ocean and the nearest major landmass is Austra .... The volcano's summit is 160m below sea level. The volcano was first located in 1976 using seismograph records, and its existence confirmed by a bathymetric survey. Moua Pihaa was seismically active from 22 to 29 April 1969, and from 21 to 23 June 1970, which suggests that submarine eruptions have occurred.

Nuku Hiva
Nuku Hiva (sometimes spelled Nukahiva or Nukuhiva) is the largest of the Marquesas Islands in French Polynesia, an overseas country of France in the Pacific Ocean. It was formerly also known as ''Île Marchand'' and ''Madison Island''. Herman Melville wrote his book '' Typee'' based on his experiences in the Taipivai valley in the eastern part of Nuku Hiva. Robert Louis Stevenson's first landfall on his voyage on the ''Casco'' was at Hatihe'u, on the north side of the island, in 1888. Geography Coast Western Nuku Hiva is characterized by a steep but fairly regular coastline, indented occasionally by small bays, leading to deep valleys, which in turn lead into the interior. There are no villages on the western side. The coastline of the eastern part of the island has few places to land by sea and takes the brunt of the ocean swells. The northern side, in contrast, is indented by deep bays, the largest of which are Anahō and Hatihe'u. A third bay, 'A'akapa, is smaller and ...

Raiatea
Raiatea or Ra'iatea ( Tahitian: ''Ra‘iātea'') is the second largest of the Society Islands, after Tahiti, in French Polynesia. The island is widely regarded as the "centre" of the eastern islands in ancient Polynesia and it is likely that the organised migrations to the Hawaiian Islands, New Zealand and other parts of East Polynesia started at Raiatea. A traditional name for the island is Havai'i, homeland of the Māori people. Situated on the southeast coast is the historical Taputapuatea marae, which was established by 1000 CE. The site was the political and religious center of eastern Polynesia for several centuries, and was inscribed on the UNESCO World Heritage List in 2017 for its historical significance. The main township on Raiatea is Uturoa, the administrative centre for the Leeward Islands (French ''Îles Sous-le-vent''). There are also colleges which serve as the main educational location for secondary schools for students from the regional islands of B ...

Teahitia
Teahitia ("Standing Fire") is a submarine volcano, located northeast of the southeast tip of Tahiti of the Society Islands in the 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 conti ..., with its peak 1600 meters below the water surface. It belongs to the Society hotspot. Teahitia's last eruption occurred in 1985. The seamount has four prominent cones. Submersible dives in 1986 and 1989 found two active hydrothermal fields on the volcano's flanks. A further dive in 2013 found ongoing hydrothermal venting. Earthquake swarms in March 1982, July 1983, December 1983, and January 1985 have been associated with submarine eruptions. On 16 March 2008 Teahitia was the epicentre of an earthquake measuring 3.2 on the Richter scale. The weak tremor was felt in Tahiti, causing the be ...

Moorea
Moorea ( or ; Tahitian: ), also spelled Moorea, is a volcanic island in French Polynesia. It is one of the Windward Islands, a group that is part of the Society Islands, northwest of Tahiti. The name comes from the Tahitian word , meaning "yellow lizard": = lizard ; (from ) = yellow. An older name for the island is ', sometimes spelled or (among other spellings that were used by early visitors before Tahitian spelling was standardized). Early Western colonists and voyagers also referred to Moorea as ''York Island'' or ''Santo Domingo''. History Prehistory According to recent archaeological evidence, the Society Islands were probably settled from Samoa and Tonga around 200 CE.Patrick V.
