Ankaratra Franzi
Ankaratra is a cinder cone volcano range located about southwest of Antananarivo, the capital city of Madagascar. It lies between the towns of Arivonimamo to the north, Ambatolampy to the east, Faratsiho to the west and Betafo to the south. It is located in the Central Highlands. The highest peak in Ankaratra is '' Mount Tsiafajavona'' ("never out of the fog"), at 2,644 metres (8,668 ft.) above sea level. Some trace of activity remains in the southernmost part of the range, creating hot springs in the area around Antsirabe. The last eruption of Ankaratra took place in the very recent Quaternary.

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 ...

Antananarivo
Antananarivo ( French: ''Tananarive'', ), also known by its colonial shorthand form Tana, is the capital and largest city of Madagascar. The administrative area of the city, known as Antananarivo-Renivohitra ("Antananarivo-Mother Hill" or "Antananarivo-Capital"), is the capital of Analamanga region. The city sits at above sea level in the center of the island, the highest national capital by elevation among the island countries. It has been the country's largest population center since at least the 18th century. The presidency, National Assembly, Senate and Supreme Court are located there, as are 21 diplomatic missions and the headquarters of many national and international businesses and NGOs. It has more universities, nightclubs, art venues, and medical services than any city on the island. Several national and local sports teams, including the championship-winning national rugby team, the Makis are based here. Antananarivo was historically the capital of the Merina peop ...

Madagascar
Madagascar (; mg, Madagasikara, ), officially the Republic of Madagascar ( mg, Repoblikan'i Madagasikara, links=no, ; french: République de Madagascar), is an island country in the Indian Ocean, approximately off the coast of East Africa across the Mozambique Channel. At Madagascar is the world's List of island countries, second-largest island country, after Indonesia. The nation is home to around 30 million inhabitants and consists of the island of Geography of Madagascar, Madagascar (the List of islands by area, fourth-largest island in the world), along with numerous smaller peripheral islands. Following the prehistoric breakup of the supercontinent Gondwana, Madagascar split from the Indian subcontinent around 90 million years ago, allowing native plants and animals to evolve in relative isolation. Consequently, Madagascar is a biodiversity hotspot; over 90% of wildlife of Madagascar, its wildlife is endemic. Human settlement of Madagascar occurred during or befo ...

Central Highlands (Madagascar)
The Central Highlands, Central High Plateau, or Hauts-Plateaux are a mountainous biogeographical region in central Madagascar. They include the contiguous part of the island's interior above 800 m (2,600 ft) altitude. The Central Highlands are separated from the Northern Highlands of the northern tip of Madagascar by a low-lying valley, the Mandritsara Window, which has apparently acted as a barrier to dispersal for species in the highlands, leading to species pairs such as ''Voalavo gymnocaudus'' and ''Voalavo antsahabensis'' in the Northern and Central Highlands. Species restricted to the Central Highlands include the bats '' Miniopterus manavi'' and '' Miniopterus sororculus''; the rodents '' Brachyuromys betsileoensis'' and ''Voalavo antsahabensis''; the tenrecs '' Hemicentetes nigriceps'' and '' Oryzorictes tetradactylus''; and the lemur '' Cheirogaleus sibreei''. Because of the continuous habitat of the Central Highlands, there is little local endemism Endemis ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Sea Level
Mean sea level (MSL, often shortened to sea level) is an average surface level of one or more among Earth's coastal bodies of water from which heights such as elevation may be measured. The global MSL is a type of vertical datuma standardised geodetic datumthat is used, for example, as a chart datum in cartography and marine navigation, or, in aviation, as the standard sea level at which atmospheric pressure is measured to calibrate altitude and, consequently, aircraft flight levels. A common and relatively straightforward mean sea-level standard is instead the midpoint between a mean low and mean high tide at a particular location. Sea levels can be affected by many factors and are known to have varied greatly over geological time scales. Current sea level rise is mainly caused by human-induced climate change. When temperatures rise, Glacier, mountain glaciers and the Ice sheet, polar ice caps melt, increasing the amount of water in water bodies. Because most of human settlem ...

Antsirabe
Antsirabe () is the third largest city in Madagascar and the capital of the Vakinankaratra region, with a population of 265,018 in 2014. In Madagascar, Antsirabe is known for its relatively cool climate (like the rest of the central region), its industry and the high concentration of pulled rickshaws or ''pousse-pousse''. It attracts around 30,000 tourists a year Etymology and names The Malagasy name ''Antsirabe'' literally means "the place of much salt". The city has the nicknames ''ville d'eau'' ('city of water' in French) and ''visy gasy'' or ''le Vichy malgache'' ('the Malagasy Vichy' in Malagasy and French respectively), referring to the presence of multiple thermal springs in the area. History The area where Antsirabe is found today was part of the Kingdom of Andrantsay which existed from the early 1600s until it was incorporated into the Imerina kingdom in the early 1800s. The area was a farming region, with production of rice, vegetables and fruit. The first No ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Quaternary
The Quaternary ( ) is the current and most recent of the three periods of the Cenozoic Era in the geologic time scale of the International Commission on Stratigraphy (ICS). It follows the Neogene Period and spans from 2.58 million years ago to the present. The Quaternary Period is divided into two epochs: the Pleistocene (2.58 million years ago to 11.7 thousand years ago) and the Holocene (11.7 thousand years ago to today, although a third epoch, the Anthropocene, has been proposed but is not yet officially recognised by the ICS). The Quaternary Period is typically defined by the cyclic growth and decay of continental ice sheets related to the Milankovitch cycles and the associated climate and environmental changes that they caused. Research history In 1759 Giovanni Arduino proposed that the geological strata of northern Italy could be divided into four successive formations or "orders" ( it, quattro ordini). The term "quaternary" was introduced by Jules Desnoye ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
