Cordillera Central (Costa Rica)
The Cordillera Central is a volcanic mountain range in central Costa Rica which continues from the Continental Divide to east of Cordillera de Tilarán. It extends 80 km from Tapezco Pass to the Turrialba Volcano and ends on the Pacuare River. It is separated from Cordillera de Tilarán by Balsa River and Platanar and Zarcero hills. The Cordillera Central is part of the American Cordillera, a chain of mountain ranges (cordillera) that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, South America and Antarctica. It contains four large volcanoes Poás (2,708 m), Barva (2,906 m), Irazú and Turrialba (3,340 m). The highest peak is Irazú at 3,432 m. South of the range lie elevated plains of central tectonic depression of Costa Rican Central Valley. Cordillera Central's four main volcanoes are protected as national parks A national park is a nature park designated for conservation (e ...

Irazú Volcano
The Irazú Volcano () is an active volcano in Costa Rica, situated in the Cordillera Central close to the city of Cartago. The name might have come from either the combination of "ara" (point) and "tzu" (thunder) or a corruption of ''Iztarú'', which was the name of an indigenous village on the flanks of the volcano. In Costa Rica it is known by the name of "El Coloso" (the Colossus) due to the catastrophes that it has unleashed in the past. The volcano's summit has several craters, one of which contains Diego de la Haya, a green crater lake of variable depth. At 11,260 feet (3,432 m), the Irazú Volcano is the highest active volcano in Costa Rica. It is thus a popular tourist spot. It is easily visited from San José, the Costa Rican capital, with a road leading right up to the summit craters and a weekly bus service to the top. The summit of the volcano also houses a few television transmitters for television stations in San José. From the top it is possible to see ...

Barva Volcano
Barva Volcano is an andesitic stratovolcano complex in central Costa Rica, 22 km north of San José, in Heredia Province. On the eastern side of the mountain is a lake in what was the volcanic crater, called "Laguna de Barva", and on the western side it has three hills on the top which are called "Las Tres Marías". It is located in the small agricultural community of Sacramento. Barva has several eruptive centres at its summit and many parasitic cones on its flanks. Its three principal summits visible from the Central Valley give it the common local name of ''Las Tres Marías'' (The Three Marys). Four pyroclastic cones are present within the 2 x 3 km caldera A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. An eruption that ejects large volumes of magma over a short period of time can cause significant detriment to the str ... at the central and northwestern part of the summit. The sou ...

Mountain Ranges Of Costa Rica
Costa Rica is located on the Central American Isthmus, surrounding the point 10° north of the equator and 84° west of the prime meridian. It has 212 km of Caribbean Sea coastline and 1,016 on the North Pacific Ocean. The area is 51,100 km2 of which 40 km2 is water. It is slightly smaller than Bosnia and Herzegovina. Geology Costa Rica is located on the Caribbean Plate. It borders the Cocos Plate in the Pacific Ocean which is being subducted beneath it. This forms the volcanoes in Costa Rica, also known as the Central America Volcanic Arc. The Caribbean Plate began its eastward migration during the Late Cretaceous. During the Late Paleocene, a local sea-level low-stand assisted by the continental uplift of the western margin of South America, resulted in a land bridge over which several groups of mammals apparently took part in an interchange. Many earthquakes in Costa Rica have occurred. Political and human geography Costa Rica shares a border with Ni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |

Hydrothermal
Hydrothermal circulation in its most general sense is the circulation of hot water (Ancient Greek ὕδωρ, ''water'',Liddell, H.G. & Scott, R. (1940). ''A Greek-English Lexicon. revised and augmented throughout by Sir Henry Stuart Jones. with the assistance of. Roderick McKenzie.'' Oxford: Clarendon Press. and θέρμη, ''heat'' ). Hydrothermal circulation occurs most often in the vicinity of sources of heat within the Earth's crust. In general, this occurs near volcanic activity, but can occur in the shallow to mid crust along deeply penetrating fault irregularities or in the deep crust related to the intrusion of granite, or as the result of orogeny or metamorphism. Hydrothermal circulation often results in hydrothermal mineral deposits. Seafloor hydrothermal circulation Hydrothermal circulation in the oceans is the passage of the water through mid-oceanic ridge systems. The term includes both the circulation of the well-known, high-temperature vent waters near the ridge c ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Fumarolic
A fumarole (or fumerole) is a vent in the surface of the Earth or another rocky planet from which hot volcanic gases and vapors are emitted, without any accompanying liquids or solids. Fumaroles are characteristic of the late stages of volcanic activity, but fumarole activity can also precede a volcanic eruption and has been used for eruption prediction. Most fumaroles die down within a few days or weeks of the end of an eruption, but a few are persistent, lasting for decades or longer. An area containing fumaroles is known as a fumarole field. The predominant vapor emitted by fumaroles is steam, formed by the circulation of groundwater through heated rock. This is typically accompanied by volcanic gases given off by magma cooling deep below the surface. These volcanic gases include sulfur compounds, such as various sulfur oxides and hydrogen sulfide, and sometimes hydrogen chloride, hydrogen fluoride, and other gases. A fumarole that emits significant sulfur compounds is some ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Poás Volcano National Park
Poás Volcano National Park () is a national park in Costa Rica that covers an area of approximately ; the summit of Poás Volcano located within the park is at an elevation of . The park was established on 25 January 1971. Depending on conditions, visitors can walk all the way to the edge of the main crater, but on 13 April 2017 the park was closed to visitors due to an explosive eruption on the evening of 12 April. Still further eruptions, including on Easter, 16 April, caused the park to be closed until August 2018. Over the years, the park has been frequently closed to visitors due to precautions because of water vapor and sulfuric acid gas emissions. The status of the park being subject to change, potential visitors should check the current conditions at the park. Poas Volcano erupted twice briefly in September 2019. The volcano is located in the Central Conservation Area located in the Alajuela Province near the Pacific coast of Costa Rica, which encompasses the area aroun ...
