Pululagua Volcano 1
Pululahua is a dormant volcano in the north of Quito Canton, Pichincha Province, Ecuador. The volcano is in the Western Cordillera of the northern Ecuadorian Andes, approximately west-southwest of Mojanda and north of Casitahua volcanoes. Pululahua's caldera is approximately 5 km wide. The volcano is within an Ecuadorian national park known as Reserva Geobotánica Pululahua. In 467 BCE, Pululahua erupted, sending volcanic ash over much of the western Ecuadorian lowland regions, which greatly reduced the expressions of the Chorrera The Chorrera culture or Chorrera tradition is a Late Formative indigenous culture that flourished between 1300 BCE and 300 BCE in Ecuador.White, Nancy ''South American Archaeology.''

Volcano
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 ...

Ecuador
Ecuador ( ; ; Quechua: ''Ikwayur''; Shuar: ''Ecuador'' or ''Ekuatur''), officially the Republic of Ecuador ( es, República del Ecuador, which literally translates as "Republic of the Equator"; Quechua: ''Ikwadur Ripuwlika''; Shuar: ''Ekuatur Nunka''), is a country in northwestern South America, bordered by Colombia on the north, Peru on the east and south, and the Pacific Ocean on the west. Ecuador also includes the Galápagos Islands in the Pacific, about west of the mainland. The country's capital and largest city is Quito. The territories of modern-day Ecuador were once home to a variety of Indigenous groups that were gradually incorporated into the Inca Empire during the 15th century. The territory was colonized by Spain during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as its own sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its mill ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mojanda
Mojanda is an inactive stratovolcano of the Eastern Cordillera of the Andes in northern Ecuador. A summit caldera, which was produced by an explosive Plinian Eruption that marked the end of Mojanda activity 200,000 years ago, is occupied by three crater lakes: Karikucha (the largest), Yanakucha, and Warmikucha. Having received protected status in 2002, they are a popular tourist destination and are about 20 minutes taxi ride from the largely indigenous town of Otavalo. Mojanda is a complex of two volcanoes which were active simultaneously. The volcanic vents are only 3 km apart. The other volcano, which produced at least two Plinian Eruptions of its own, is known as Fuya Fuya. Fuya Fuya partially collapsed around 165,000 years ago, creating a large caldera to the west. A new volcanic cone and other lava domes subsequently extruded inside the caldera, probably during the Late Pleistocene. The high altitude grasslands and shrublands of Mojanda, which ...

Reserva Geobotánica Pululahua
Reserva Geobotánica Pululahua (''Pululahua Geobotanical Reserve'') (''Cloud of Water Geobontanical Reserve'') is a protected area around Pululahua Volcano in the north of Quito Canton, Pichincha Province, Ecuador. It is 17 km north of Quito, in the northwestern part of the Pomasqui Valley Pomasqui Valley is a valley on the northern outskirts of Quito, Ecuador. It is located on the equator, the so-called "Mitad del Mundo" ("Middle of the World"), at an altitude of around above sea level. Hot and semi-arid, it is formed by a river t .... The most notable feature of this site is "el cráter de Pululahua", which is one of only two volcanic craters in the world inhabited by humans (and the only one that is farmed). Often, this reserve is shrouded in a thick layer of clouds or fog. The land here is extremely fertile because it is volcanic (igneous) soil and, as mentioned earlier, is used to cultivate crops.

Chorrera Culture
The Chorrera culture or Chorrera tradition is a Late Formative indigenous culture that flourished between 1300 BCE and 300 BCE in Ecuador.White, Nancy ''South American Archaeology.'' (retrieved 1 June 2011) Chorrera culture was one of the most widespread cultures in pre-Columbian Ecuador, spanning the Pacific lowlands to the Andean highlands,Zeidler 468 and even into southern Colombia. Regional divisions Due to variations in ceramics and other material culture, Chorrera culture is divided into regional variants. These include: *Mafa Phase, northern Esmeraldas Province *Tachina Phase, southern Esmeraldas Province *Tabuchula Phase, northern Manabí Province *Engoroy Phase, Santa Elena Peninsula and Guayas coastal region *Chorrera proper, Guayas River Basin *Early Jubones Phase, southeastern Guaya and western Azuay Province *Arenillas Phase, El Oro Province. Other regions exhibit a strong Chorrera influence. Ceramics The hallmark of Chorrera culture is its ceramic traditions, wh ...

Cotocollao Culture
The Cotocollao culture were an indigenous Pre-Columbian culture that inhabited the valley that is now the Quito area, in Ecuador. Introduction The Cotocollao natives were the first inhabitants of the mountains of what is now Ecuador. They lived approximately 1,500 to 500 years BCE, in an era known as the ''Formative Period''. Lifestyle The Cotocollao lived on farming, cultivating corn, beans, quinoa, potatoes and Lupin beans. They also hunted deer, rabbit, guanta, puma, wolf, guinea pig and doves. They lived in small villages of rectangular huts of lath and mud with straw thatching. They wore clothing woven from cotton. Artwork Probably the most distinguishing feature of the Cotocollao natives was their ability to create ceramic artwork. They made ceramics that were more for decoration than for their usefulness. It is not known whether or not they had a special place inside their houses to make ceramic artwork or not. To make the ceramic, the Cotocollaos used a paste made ...

Calderas Of Ecuador
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcano eruption. When large volumes of magma are erupted over a short time, structural support for the rock above the magma chamber is gone. The ground surface then collapses into the emptied or partially emptied magma chamber, leaving a large depression at the surface (from one to dozens of kilometers in diameter). Although sometimes described as a crater, the feature is actually a type of sinkhole, as it is formed through subsidence and collapse rather than an explosion or impact. Compared to the thousands of volcanic eruptions that occur each century, the formation of a caldera is a rare event, occurring only a few times per century. Only seven caldera-forming collapses are known to have occurred between 1911 and 2016. More recently, a caldera collapse occurred at Kīlauea, Hawaii in 2018. Etymology The term ''caldera'' comes from Spanish ', and Latin ', meaning "coo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
