Arenal Volcano
Arenal Volcano ( es, Volcán Arenal) is an active andesitic stratovolcano in north-western Costa Rica around northwest of San José, in the province of Alajuela, canton of San Carlos, and district of La Fortuna. The Arenal volcano measures at least high. It is conically shaped with a crater in diameter. Geologically, Arenal is considered a young volcano and it is estimated to be less than 7,500 years old. It is also known as "Pan de Azúcar", "Canaste", "Volcan Costa Rica", "Volcan Río Frío" or "Guatusos Peak". The volcano was dormant for hundreds of years and exhibited 2 craters at its summit, with minor fumaroles activity, covered by dense vegetation. In 1968 it erupted unexpectedly, destroying the small town of Tabacón. Due to the eruption three more craters were created on the western flanks but only one of them still exists today. Arenal's eruption from 1968 to 2010 is the tenth longest duration volcanic eruption on Earth since 1750. Since 2010, Arenal has been d ...

Alajuela is composed of 16 cantons, which are divided into 111 districts. It covers an area of 9,757.53 square kilometers. The provincial capital is Alajuela. Other large cities include Quesada, Aguas Zarcas, Naranjo, Zarcero, Orotina, Sarchí Norte, Upala, San Ramón, Grecia and Los Chiles. Provincial history Pre-Columbia and the arrival of the Spanish Costa Rica has been inhabited for nearly 10,000 years, but little is known of its pre-Columbian history. Alajuela was occupied by several indigenous groups just before the arrival of the Spanish. Despite being between two major civilizations, indigenous groups sparsely populated the area.undefinedISLS: Br ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Rincón De La Vieja Volcano
Rincón de la Vieja is an active andesitic complex volcano in north-western Costa Rica, about from Liberia, in the province of Guanacaste. Toponymy Its name means "The Old Woman's Corner", or "Old Woman’s Nook" a reference to a local legend about princess Curabanda whose lover Mixcoac, chief of a neighboring enemy tribe, who was thrown into the crater by her father Curabande, when he learned about their affair. She went on living on the side of the volcano, giving birth to a son. To be with its father, she threw her son into the volcano, too. She continued to live on the volcano and became a recluse living on the mountain, and was credited with powers of healing. Rincón de la Vieja stands above sea level, and its summit is the highest point in Rincón de la Vieja National Park. It erupted most recently in June 2021. The volcano has many fumaroles and hot springs on its slopes. It is formed by felsic lava. Rincón de la Vieja is one of six active Costa Rican volcanoes: the o ...

Lava Dome
In volcanology, a lava dome is a circular mound-shaped protrusion resulting from the slow extrusion of viscous lava from a volcano. Dome-building eruptions are common, particularly in convergent plate boundary settings. Around 6% of eruptions on Earth are lava dome forming. The geochemistry of lava domes can vary from basalt (e.g. Semeru, 1946) to rhyolite (e.g. Chaiten, 2010) although the majority are of intermediate composition (such as Santiaguito, dacite-andesite, present day) The characteristic dome shape is attributed to high viscosity that prevents the lava from flowing very far. This high viscosity can be obtained in two ways: by high levels of silica in the magma, or by degassing of fluid magma. Since viscous basaltic and andesitic domes weather fast and easily break apart by further input of fluid lava, most of the preserved domes have high silica content and consist of rhyolite or dacite. Existence of lava domes has been suggested for some domed structures on the Mo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Pleistocene
The Pleistocene ( , often referred to as the ''Ice age'') is the geological Epoch (geology), epoch that lasted from about 2,580,000 to 11,700 years ago, spanning the Earth's most recent period of repeated glaciations. Before a change was finally confirmed in 2009 by the International Union of Geological Sciences, the cutoff of the Pleistocene and the preceding Pliocene was regarded as being 1.806 million years Before Present (BP). Publications from earlier years may use either definition of the period. The end of the Pleistocene corresponds with the end of the last glacial period and also with the end of the Paleolithic age used in archaeology. The name is a combination of Ancient Greek grc, label=none, πλεῖστος, pleīstos, most and grc, label=none, καινός, kainós (latinized as ), 'new'. At the end of the preceding Pliocene, the previously isolated North and South American continents were joined by the Isthmus of Panama, causing Great American Interchang ...

Hydroelectric Power
Hydroelectricity, or hydroelectric power, is electricity generated from hydropower (water power). Hydropower supplies one sixth of the world's electricity, almost 4500 TWh in 2020, which is more than all other renewable sources combined and also more than nuclear power. Hydropower can provide large amounts of low-carbon electricity on demand, making it a key element for creating secure and clean electricity supply systems. A hydroelectric power station that has a dam and reservoir is a flexible source, since the amount of electricity produced can be increased or decreased in seconds or minutes in response to varying electricity demand. Once a hydroelectric complex is constructed, it produces no direct waste, and almost always emits considerably less greenhouse gas than fossil fuel-powered energy plants.

Lake Arenal
Lake Arenal ( es, Lago Arenal) is a lake which is situated in the northern highlands of Costa Rica. It is currently the largest lake in Costa Rica at . Its depth varies between 30 and 60 meters (100–200 feet) seasonally. The town of Arenal was relocated to higher ground when the lake was expanded in 1979. The old towns of Arenal and Tronadora now lie abandoned at the bottom of the lake, with the new town of Arenal existing to the northeast on the lake. Hydroelectricity Lake Arenal was tripled in size with the construction of the Arenal dam in 1979, which exists at the eastern end of the lake. This hydroelectric project exists at the western end of the lake and is strategically important to Costa Rica, initially generating 70% of the country's electricity, now closer to 17%, and was also a driving force behind Costa Rica's green energy policy. Wildlife Fish species in Lake Arenal include the machaca and the rainbow bass. There are also many species of plants, 120 ...

Drainage Divide
A drainage divide, water divide, ridgeline, watershed, water parting or height of land is elevated terrain that separates neighboring drainage basins. On rugged land, the divide lies along topographical ridges, and may be in the form of a single range of hills or mountains, known as a dividing range. On flat terrain, especially where the ground is marshy, the divide may be difficult to discern. A triple divide is a point, often a summit, where three drainage basins meet. A ''valley floor divide'' is a low drainage divide that runs across a valley, sometimes created by deposition or stream capture. Major divides separating rivers that drain to different seas or oceans are continental divides. The term ''height of land'' is used in Canada and the United States to refer to a drainage divide. It is frequently used in border descriptions, which are set according to the "doctrine of natural boundaries". In glaciated areas it often refers to a low point on a divide where it is ...
