Poás Volcano
The Poás Volcano, ( es, Volcán Poás), is an active stratovolcano in central Costa Rica and is located within Poas Volcano National Park. It has erupted 40 times since 1828, including April 2017 when visitors and residents were evacuated. The volcano and surrounding park were closed for nearly 17 months, with a 2.5 kilometer safety perimeter established around the erupting crater. As of September 1, 2018 the park has reopened with limited access only to the crater observation area and requires a reservation to be made on the National Park Website. Adjacent trails to Lake Botos as well as the museum at the visitor center remained closed. The volcano erupted briefly twice in September 2019. Crater lakes There are two crater lakes near the summit. The northern lake is known as the ''Laguna Caliente'' ("hot lagoon") and is located at a height of 2,300 m in a crater approximately 0.3 km wide and 30 m deep. It is one of the world's most acidic lakes. The acidity ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Landslide
Landslides, also known as landslips, are several forms of mass wasting that may include a wide range of ground movements, such as rockfalls, deep-seated grade (slope), slope failures, mudflows, and debris flows. Landslides occur in a variety of environments, characterized by either steep or gentle slope gradients, from mountain ranges to coastal cliffs or even underwater, in which case they are called submarine landslides. Gravity is the primary driving force for a landslide to occur, but there are other factors affecting slope stability that produce specific conditions that make a slope prone to failure. In many cases, the landslide is triggered by a specific event (such as a heavy rainfall, an earthquake, a slope cut to build a road, and many others), although this is not always identifiable. Causes Landslides occur when the slope (or a portion of it) undergoes some processes that change its condition from stable to unstable. This is essentially due to a decrease in the She ...

Active Volcanoes
An active volcano is a volcano which is either erupting or is likely to erupt in the future. An active volcano which is not currently erupting is known as a dormant volcano. Overview Tlocene Epoch. Most volcanoes are situated on the Pacific Ring of Fire. An estimated 500 million people live near active volcanoes. ''Historical time'' (or recorded history) is another timeframe for ''active''. However, the span of recorded history differs from region to region. In China and the Mediterranean, it reaches back nearly 3,000 years, but in the Pacific Northwest of the United States and Canada, it reaches back less than 300 years, and in Hawaii and New Zealand it is only around 200 years. The incomplete ''Catalogue of the Active Volcanoes of the World'', published in parts between 1951 and 1975 by the International Association of Volcanology, uses this definition, by which there are more than 500 active volcanoes. , the Smithsonian Global Volcanism Program recognizes 560 volcanoes with ...

Stratovolcanoes Of Costa Rica
A stratovolcano, also known as a composite volcano, is a conical volcano built up by many layers (strata) of hardened lava and tephra. Unlike shield volcanoes, stratovolcanoes are characterized by a steep profile with a summit crater and periodic intervals of explosive eruptions and effusive eruptions, although some have collapsed summit craters called calderas. The lava flowing from stratovolcanoes typically cools and hardens before spreading far, due to high viscosity. The magma forming this lava is often felsic, having high-to-intermediate levels of silica (as in rhyolite, dacite, or andesite), with lesser amounts of less-viscous mafic magma. Extensive felsic lava flows are uncommon, but have travelled as far as . Stratovolcanoes are sometimes called composite volcanoes because of their composite stratified structure, built up from sequential outpourings of erupted materials. They are among the most common types of volcanoes, in contrast to the less common shield volcanoes. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Fumarole
A fumarole (or fumerole) is a vent in the surface of the Earth or other 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] |
Poás Volcano National Park
Poás Volcano National Park ( es, Parque Nacional Volcán Poás) is a national park in Costa Rica that covers an area of approximately ; the summit is . It 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 around the Poás Volcano. The main cr ...

Luis Guillermo Solis
Luis is a given name. It is the Spanish form of the originally Germanic name or . Other Iberian Romance languages have comparable forms: (with an accent mark on the i) in Portuguese and Galician, in Aragonese and Catalan, while is archaic in Portugal, but common in Brazil. Origins The Germanic name (and its variants) is usually said to be composed of the words for "fame" () and "warrior" () and hence may be translated to ''famous warrior'' or "famous in battle". According to Dutch onomatologists however, it is more likely that the first stem was , meaning fame, which would give the meaning 'warrior for the gods' (or: 'warrior who captured stability') for the full name.J. van der Schaar, ''Woordenboek van voornamen'' (Prisma Voornamenboek), 4e druk 1990; see also thLodewijs in the Dutch given names database Modern forms of the name are the German name Ludwig and the Dutch form Lodewijk. and the other Iberian forms more closely resemble the French name Louis, a derivati ...

Subaerial Eruption
A subaerial eruption is any sort of volcanic eruption that occurs on the Earth's surface, or in the open air subaerial, 'under the air', and not underwater or underground. They generally produce pyroclastic flows, lava fountains, and lava flows, which are commonly classified in different subaerial eruption types, including Plinian eruption, Plinian, Peléan eruption, Peléan, and Hawaiian eruptions. Subaerial eruptions contrast with Wiktionary:subaqueous, subaqueous, submarine eruption, submarine and subglacial eruptions which all originate below differing forms of a water surface.

Sulfur Dioxide
Sulfur dioxide (IUPAC-recommended spelling) or sulphur dioxide (traditional Commonwealth English) is the chemical compound with the formula . It is a toxic gas responsible for the odor of burnt matches. It is released naturally by volcanic activity and is produced as a by-product of copper extraction and the burning of sulfur- bearing fossil fuels. Structure and bonding SO2 is a bent molecule with ''C''2v symmetry point group. A valence bond theory approach considering just ''s'' and ''p'' orbitals would describe the bonding in terms of resonance between two resonance structures. The sulfur–oxygen bond has a bond order of 1.5. There is support for this simple approach that does not invoke ''d'' orbital participation. In terms of electron-counting formalism, the sulfur atom has an oxidation state of +4 and a formal charge of +1. Occurrence Sulfur dioxide is found on Earth and exists in very small concentrations and in the atmosphere at about 1 ppm. On other planets, ...
