Volcanoes
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 pa ...

Nevado Del Ruiz
The Nevado del Ruiz (), also known as La Mesa de Herveo ( en, Mesa of Herveo, the name of the nearby town) is a volcano on the border of the departments of Caldas and Tolima in Colombia, about west of the capital city Bogotá. It is a stratovolcano composed of many layers of lava alternating with hardened volcanic ash and other pyroclastic rocks. Volcanic activity at Nevado del Ruiz began about two million years ago, since the Early Pleistocene or Late Pliocene, with three major eruptive periods. The current volcanic cone formed during the present eruptive period, which began 150,000 years ago. The volcano usually generates Vulcanian to Plinian eruptions, which produce swift-moving currents of hot gas and rock called pyroclastic flows. These eruptions often cause massive lahars (mud and debris flows), which pose a threat to human life and the environment. The impact of such an eruption is increased as the hot gas and lava melt the mountain's snowcap, adding large quantitie ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Andean Volcanic Belt
The Andean Volcanic Belt is a major volcanic belt along the Andean cordillera in Argentina, Bolivia, Chile, Colombia, Ecuador, and Peru. It is formed as a result of subduction of the Nazca Plate and Antarctic Plate underneath the South American Plate. The belt is subdivided into four main volcanic zones which are separated by volcanic gaps. The volcanoes of the belt are diverse in terms of activity style, products, and morphology. While some differences can be explained by which volcanic zone a volcano belongs to, there are significant differences within volcanic zones and even between neighboring volcanoes. Despite being a type location for calc-alkalic and subduction volcanism, the Andean Volcanic Belt has a broad range of volcano-tectonic settings, as it has rift systems and extensional zones, transpressional faults, subduction of mid-ocean ridges and seamount chains as well as a large range of crustal thicknesses and magma ascent paths and different amounts of crustal assim ...

Geology Of Colombia
Geology of Colombia refers to the geological composition of the Republic of Colombia that determines its geography. Most of the emerged territory of Colombia covers vast areas within the South American plate, whereas much submerged territory lies within the Caribbean plate and the Nazca plate. Geologic history As in the rest of South America, a combination of external and internal tectonic, volcanic, and glacial forces over the eons formed Colombia's present-day geology.Bushnell, David and Rex A. Hudson. "Geology". I''Colombia: A Country Study''(Rex A. Hudson, ed.), pp. 70-71. Library of Congress Federal Research Division (2010). Island-like outcrops of metamorphic rocks in the eastern Llanos are visible remnants of Precambrian times. During the 289-million-year-long Paleozoic Era, which began 539 million years ago, the ocean invaded the area which is exposed in Colombia's Andean zone, as subterranean volcanic eruptions in the western part of the country spouted lava.

List Of Fossiliferous Stratigraphic Units In Colombia
Several stratigraphic units in Colombia have provided fossils. The richest formations are the Devonian Cuche and Floresta Formations, the Cretaceous Paja Formation, the Paleocene Cerrejón Formation and the Miocene La Venta site. The latter is the richest Konzentrat-Lagerstätte in northern South America and comprises the formations of the Honda Group. __TOC__ Fossiliferous stratigraphic units ''Formations are ordered according to their youngest age'' Proposed reclassification of South American gomphotheres Some authors, Lucas, Mothé, Avilla et al., propose a reclassification of the South American gomphotheres as follows:Lucas, 2013Mothé et al., 2012Mothé et al., 2016aMothé et al., 2016b * '' Stegomastodon'' is an exclusively North American genus * ''Haplomastodon'' is a South American genus, but synonymous with ''Notiomastodon'' * as ''Notiomastodon'' was defined earlier, all ''Haplomastodon'' species should be considered part of ''Notiomastodon'' * all fo ...

List Of Earthquakes In Colombia
This is a list of earthquakes in Colombia. Colombia is a seismically active country and has a large seismic risk in many areas of its territory due to its location at the boundaries of the Malpelo, Panama, Caribbean, North Andes (where most earthquakes occurred) and South American Plates along the Pacific Ring of Fire. The southeastern and extreme eastern portions of Colombia are not as seismically active as the rest of the country. The first historically registered earthquake felt in Colombia occurred on September 11, 1530, around 10:00 AM, probably with the epicentre near Cumaná, Venezuela. The earthquake was documented by Gonzalo Fernández de Oviedo y Valdés in his work ''La Historia general de las Indias'' and by friar Bartolomé de las Casas in his book ''Historia de Las Indias''.Ramírez, 1975, p.63 The first documented earthquake with its epicentre in present-day Colombia territory took place in 1566,Ramírez, 1975, p.65 with the epicentre estimated around Santander ...

Puracé
Puracé is an andesitic stratovolcano located in the Puracé National Natural Park in the Cauca Department, Colombia. It is part of the North Volcanic Zone of the Andean Volcanic Belt. The volcano is located at the intersection of the Coconucos and Morras Faults.Plancha 365, 2003 It is one of the most active volcanoes in Colombia. Large explosive eruptions occurred in 1849, 1869, 1885, 1949, 1950, 1956, and 1957. There were about a dozen eruptions in the 20th century, the most recent being in 1977.
