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 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 ... 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 and Cotocollao cultures.Zeidler 471 Notes References *Zeidler, J.

Volcano
A volcano is commonly defined as a vent or fissure 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 because most of Earth's plate boundaries are underwater, most volcanoes 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 resulting from divergent tectonic activity are usually non-explosive whereas those resulting from convergent tectonic activity cause violent eruptions."Mid-ocean ridge tectonics, volcanism and geomorphology." Geology 26, no. 455 (2001): 458. https://macdonald.faculty.geol.ucsb.edu/papers/Macdonald%20Mid-Ocean%20Ridge%20Tectonics.pdf Volcanoes can also form where there is str ...

Pichincha Province
Pichincha () is a province of Ecuador located in the northern Sierra region; its capital and largest city is Quito. It is bordered by Imbabura and Esmeraldas to the north, Cotopaxi and Santo Domingo de los Tsáchilas to the south, Napo and Sucumbíos to the east, and Esmeraldas and Santo Domingo de los Tsáchilas to the west. Prior to 2008, the canton Santo Domingo de los Colorados was part of the Pichincha Province. It has since become its own province, Santo Domingo de los Tsáchilas. The province is home to many rose plantations, which make up the bulk of Ecuador's floriculture industry.

Ecuador
Ecuador, officially the Republic of Ecuador, 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. It also includes the Galápagos Province which contains the Galapagos Islands in the Pacific, about west of the mainland. The country's Capital city, capital is Quito and its largest city is Guayaquil. The land that comprises modern-day Ecuador was once home to several groups of Indigenous peoples in Ecuador, indigenous peoples that were gradually incorporated into the Inca Empire during the 15th century. The territory was Spanish colonization of the Americas, colonized by the Spanish Empire during the 16th century, achieving independence in 1820 as part of Gran Colombia, from which it emerged as a sovereign state in 1830. The legacy of both empires is reflected in Ecuador's ethnically diverse population, with most of its million people being mestizos, followed by large minorities of Europe ...

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 lie ...

Casitahua
Casitahua (less frequent spelling: ''Casitagua'') is a dormant, eroded stratovolcano in the north of Quito Canton, Pichincha Province, Ecuador, with a height of . The volcano is in the Western Cordillera of the northern Ecuadorian Andes, between Pululagua Volcano to the north and Pichincha Volcano approximately to the southwest. Casitahua's caldera is open approximately towards the west-northwest. The volcano has last been active in the Pleistocene era. Casitahua is surrounded by the urban parishes El Condado and Cotocollao of the city of Quito to the south, and by the rural parishes Calacalí to the northwest and San Antonio San Antonio ( ; Spanish for " Saint Anthony") is a city in the U.S. state of Texas and the most populous city in Greater San Antonio.

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 Quito (; ), officially San Francisco de Quito, is the capital city, capital and second-largest city of Ecuador, with an estimated population of 2.8 million in its metropolitan area. It is also the capital of the province of Pichincha Province, P ..., in the northwestern part of the Pomasqui Valley. 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 Andes, 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 traditio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Calderas Of Ecuador
A caldera ( ) is a large cauldron-like hollow that forms shortly after the emptying of a magma chamber in a volcanic eruption. An eruption that ejects large volumes of magma over a short period of time can cause significant detriment to the structural integrity of such a chamber, greatly diminishing its capacity to support its own roof and any substrate or rock resting above. 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 over the course of a century, the formation of a caldera is a rare event, occurring only a few times within a given window of 100 years. Only eight caldera-forming collapses are known to have occurred between ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
