Volcán Acatenango
Acatenango is a stratovolcano in Guatemala, close to the city of Antigua. The volcano has two peaks, ''Pico Mayor'' (Highest Peak) and ''Yepocapa'' (3,880 m) which is also known as Tres Hermanas (Three Sisters). Acatenango is joined with Volcán de Fuego and collectively the volcano complex is known as La Horqueta. Description The Fuego-Acatenango massif comprises a string of five or more volcanic vents along a north–south trend that is perpendicular to that of the Central American Volcanic Arc in Guatemala. From north to south, known centres of volcanism are Ancient Acatenango, Yepocapa, Pico Mayor de Acatenango, Meseta, and Fuego. Volcanism along the trend stretches back more than 200,000 years. Although many of the centres have been active contemporaneously, there is a general sequence of younger volcanism, from north to south along the trend. This massive volcano complex towers more than 3,500 metres above the Pacific coastal plain to the south and 2,000 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Volcán De Fuego
Volcán de Fuego (; Spanish for "Volcano of Fire", often shortened to Fuego) or Chi Q'aq' (Kaqchikel for "where the fire is") is an active stratovolcano in Guatemala, on the borders of Chimaltenango, Escuintla and Sacatepéquez departments. It sits about west of Antigua, one of Guatemala's most famous cities and a tourist destination. It has erupted frequently since the Spanish conquest, most recently in June and November 2018, 23 September 2021, and 11 December 2022. Fuego is famous for being almost constantly active at a low level. Small gas and ash eruptions occur every 15 to 20 minutes, but larger eruptions are rare. Andesite and basalt lava types dominate, and recent eruptions have tended to be more mafic than older ones. The volcano is joined with Acatenango and collectively the complex is known as La Horqueta. Early expeditions In 1881, French writer Eugenio Dussaussay climbed the volcano, then practically unexplored. First, he needed to ask for permission to ...

Pyroclastic Flow
A pyroclastic flow (also known as a pyroclastic density current or a pyroclastic cloud) is a fast-moving current of hot gas and volcanic matter (collectively known as tephra) that flows along the ground away from a volcano at average speeds of but is capable of reaching speeds up to . The gases and tephra can reach temperatures of about . Pyroclastic flows are the most deadly of all volcanic hazards and are produced as a result of certain explosive eruptions; they normally touch the ground and hurtle downhill, or spread laterally under gravity. Their speed depends upon the density of the current, the volcanic output rate, and the gradient of the slope. Origin of term The word ''pyroclast'' is derived from the Greek (''pýr''), meaning "fire", and (''klastós''), meaning "broken in pieces". A name for pyroclastic flows which glow red in the dark is (French, "burning cloud"); this was notably used to describe the disastrous 1902 eruption of Mount Pelée on Martinique, a French ...

Protected Areas Of Guatemala
Protection is any measure taken to guard a thing against damage caused by outside forces. Protection can be provided to physical objects, including organisms, to systems, and to intangible things like civil and political rights. Although the mechanisms for providing protection vary widely, the basic meaning of the term remains the same. This is illustrated by an explanation found in a manual on electrical wiring: Some kind of protection is a characteristic of all life, as living things have evolved at least some protective mechanisms to counter damaging environmental phenomena, such as ultraviolet light. Biological membranes such as bark on trees and skin on animals offer protection from various threats, with skin playing a key role in protecting organisms against pathogens and excessive water loss. Additional structures like scales and hair offer further protection from the elements and from predators, with some animals having features such as spines or camouflage s ...

Mountains Of Guatemala
A mountain is an elevated portion of the Earth's crust, generally with steep sides that show significant exposed bedrock. Although definitions vary, a mountain may differ from a plateau in having a limited summit area, and is usually higher than a hill, typically rising at least 300 metres (1,000 feet) above the surrounding land. A few mountains are isolated summits, but most occur in mountain ranges. Mountains are formed through tectonic forces, erosion, or volcanism, which act on time scales of up to tens of millions of years. Once mountain building ceases, mountains are slowly leveled through the action of weathering, through slumping and other forms of mass wasting, as well as through erosion by rivers and glaciers. High elevations on mountains produce colder climates than at sea level at similar latitude. These colder climates strongly affect the ecosystems of mountains: different elevations have different plants and animals. Because of the less hospitable ...

Subduction Volcanoes
Subduction is a geological process in which the oceanic lithosphere is recycled into the Earth's mantle at convergent boundaries. Where the oceanic lithosphere of a tectonic plate converges with the less dense lithosphere of a second plate, the heavier plate dives beneath the second plate and sinks into the mantle. A region where this process occurs is known as a subduction zone, and its surface expression is known as an arc-trench complex. The process of subduction has created most of the Earth's continental crust. Rates of subduction are typically measured in centimeters per year, with the average rate of convergence being approximately two to eight centimeters per year along most plate boundaries. Subduction is possible because the cold oceanic lithosphere is slightly denser than the underlying asthenosphere, the hot, ductile layer in the upper mantle underlying the cold, rigid lithosphere. Once initiated, stable subduction is driven mostly by the negative buoyancy of the de ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Stratovolcanoes Of Guatemala
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] |
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 ...

Sierra Madre De Chiapas
The Sierra Madre de Chiapas is a major mountain range in Central America. It crosses El Salvador, Guatemala, Mexico and Honduras. The Sierra Madre de Chiapas is part of the American Cordillera, a chain of mountain ranges that consists of an almost continuous sequence of mountain ranges that form the western "backbone" of North America, Central America, and South America. Geography The range runs northwest–southeast from the state of Chiapas in Mexico, across western Guatemala, into El Salvador and Honduras. Most of the volcanoes of Guatemala, part of the Central America Volcanic Arc, are within the range. A narrow coastal plain lies south of the range, between the Sierra Madre and the Pacific Ocean. To the north lie a series of highlands and depressions, including the Chiapas Depression, which separates the Sierra Madre from the Chiapas Plateau, the Guatemalan Highlands, and Honduras' interior highlands. The range forms the main drainage divide between the Pacific and Atlanti ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Sacatepéquez Department
Sacatepéquez () is one of the 22 departments of Guatemala. The name comes from Sacatepéquez, a city from November 21, 1542, until July 29, 1773, when it was destroyed by the 1773 Guatemalan Earthquake (Santa Marta Earthquake). Sacatepéquez means ''grasshill'' in the Nahuatl language. The capital of Sacatepéquez is Antigua Guatemala which is home to an extensive textile marketplace. Other important cities include Ciudad Vieja and San Lucas Sacatepéquez, which also hosts a marketplace and is a culinary attraction. The Chajoma were a group of indigenous people who were Kaqchikel speaking Indians identified Mixco Viejo as their capital, and spread throughout the Sacatepequez Department until their capital was moved to Ciudad Vieja, in Antigua. Name Sacatepéquez has also been spelled ''Zacatepeques''. Population Sacatepéquez Department has a population of 330,469 (2018 census). In 1850, the area had a population of an estimated 56,000.
