The Eifel is a low mountain range in western Germany, eastern Belgium and northern Luxembourg. It occupies parts of southwestern North Rhine-Westphalia, northwestern Rhineland-Palatinate and the southern area of the German-speaking Community of Belgium.
The Ring of Fire is a tectonic belt, about 40,000 km (25,000 mi) long and up to about 500 km (310 mi) wide, which circumscribes the Pacific Ocean. It contains between 750 and 915 volcanoes, around two-thirds of the world total, and 90% of the world's earthquakes, including 81% of its largest, take place within the belt.
Vulkaneifel is a district (Kreis) in the northwest of the state Rhineland-Palatinate, Germany. It is the least densely populated district in the state and the fourth most sparsely populated district in Germany. The administrative centre of the district is in Daun. Neighboring districts are Euskirchen, Ahrweiler, Mayen-Koblenz, Cochem-Zell, Bernkastel-Wittlich, and Bitburg-Prüm.
The Auckland volcanic field is an area of monogenetic volcanoes covered by much of the metropolitan area of Auckland, New Zealand's largest city, located in the North Island. The approximately 53 volcanoes in the field have produced a diverse array of maars, tuff rings, scoria cones, and lava flows. With the exception of Rangitoto, no volcano has erupted more than once, but the other eruptions lasted for various periods ranging from a few weeks to several years. Rangitoto erupted several times and recently twice; in an eruption that occurred about 600 years ago, followed by a second eruption approximately 50 years later. The field is fuelled entirely by basaltic magma, unlike the explosive subduction-driven volcanism in the central North Island, such as at Mount Ruapehu and Lake Taupō.
Mount Asama is an active complex volcano in central Honshū, the main island of Japan. The volcano is the most active on Honshū. The Japan Meteorological Agency classifies Mount Asama as rank A. It stands 2,568 metres (8,425 ft) above sea level on the border of Gunma and Nagano prefectures. It is included in 100 Famous Japanese Mountains.
Mount Aso, is also known as Aso Volcano and in this sense is the largest active volcano in Japan, and is among the largest in the world. Common use relates often only to the somma volcano in the centre of the Aso Caldera. It stands in Aso Kujū National Park in Kumamoto Prefecture, on the island of Kyushu. Its tallest peak, Takadake, is 1,592 meters (5,223 ft) above sea level. Mount Aso is in a fairly large caldera with a circumference of around 120 km (75 mi), although sources vary on the exact distance.
A maar is a broad, low-relief volcanic crater caused by a phreatomagmatic eruption. A maar characteristically fills with water to form a relatively shallow crater lake, which may also be called a maar.
The Trans-Mexican Volcanic Belt, also known as the Transvolcanic Belt and locally as the Sierra Nevada, is an active volcanic belt that covers central-southern Mexico. Several of its highest peaks have snow all year long, and during clear weather, they are visible to a large percentage of those who live on the many high plateaus from which these volcanoes rise.
Sangay is an active stratovolcano in central Ecuador. It exhibits mostly strombolian activity. Geologically, Sangay marks the southern boundary of the Northern Volcanic Zone, and its position straddling two major pieces of crust accounts for its high level of activity. Sangay's approximately 500,000-year-old history is one of instability; two previous versions of the mountain were destroyed in massive flank collapses, evidence of which still litters its surroundings today.
The Central American Volcanic Arc is a chain of volcanoes which extends parallel to the Pacific coastline of the Central American Isthmus, from Mexico to Panama. This volcanic arc, which has a length of 1,100 kilometers is formed by an active subduction zone, with the Cocos Plate subducting underneath the Caribbean Plate. The region has been volcanically and geologically active for at least the past several million years. Numerous volcanoes are spread throughout various Central American countries; many have been active in the geologic past, some more so than others.
Mount Price is a small stratovolcano in the Garibaldi Ranges of the Pacific Ranges in southwestern British Columbia, Canada. It has an elevation of 2,049 metres and rises above the surrounding landscape on the western side of Garibaldi Lake in New Westminster Land District. The mountain contains a number of subfeatures, including Clinker Peak on its western flank, which was the source of two thick lava flows between 15,000 and 8,000 years ago that ponded against glacial ice. These lava flows are structurally unstable, having produced large landslides as recently as the 1850s. A large provincial park surrounds Mount Price and other volcanoes in its vicinity. It lies within an ecological region that surrounds much of the Pacific Ranges.
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 assimilations.
The Eifel hotspot is a volcanic hotspot in Western Germany. It is one of many recent volcanic formations in and around the Eifel mountain range and includes the volcanic field known as Volcanic Eifel. Although the last eruption occurred around 10,000 years ago, the presence of escaping volcanic gases in the region indicates that it is still weakly active.
The National Polytechnic School, also known as EPN, is a public university in Quito, Ecuador. The campus, called "José Rubén Orellana", is located at the sector center-oriental of Quito. It occupies an area of 15.2 hectares and has a built area of around 62,000 metres2. Its student body numbers approximately 10,000 of which thirty percent are women. The main campus encompasses ten teaching and research faculties, in addition to four technical and specialized institutes. EPN was founded in 1869 with the aim of becoming the first technical and technological center in the country. Since its beginnings, EPN adopted the polytechnic university model, which stresses laboratory instruction in applied science and engineering. At the campus, there are some libraries with a content primarily oriented to engineering and scientific topics.
The Volcanic Eifel or Vulkan Eifel is a region in the Eifel Mountains in Germany that is defined to a large extent by its volcanic geological history. Characteristic of this volcanic field are its typical explosion crater lakes or maars, and numerous other signs of volcanic activity such as volcanic tuffs, lava streams and volcanic craters like the Laacher See. The Volcanic Eifel is still volcanically active today. One sign of this activity is the escaping gases in the Laacher See.
The Volcano Park in Mayen-Koblenz is a geopark in the rural district of Mayen-Koblenz in the eastern Vulkan Eifel, Germany. It was founded in 1996 and wraps around the Laacher See. Together with the Volcano Park, Brohltal/Laacher See and the Vulkan Eifel Nature and Geo-Park, it forms part of the national Eifel Volcano Land Geo-Park. The three parks are connected by the 280-kilometre-long German Volcano Route.
Devana Chasma is a weak extensional rift zone on Venus, with a length of 4000 km, a width of 150–250 km, and a depth reaching 5 km. Most of the faults are facing north–south. The rift is located in Beta Regio, a 3000 km rise created by volcanic activity. Mantle plumes rising from the bottom are the reason behind the formation of the rift zone. The slow extension rates in the rift may be driven by the same reason.
The German Volcano Route or, less commonly, German Volcano Road is a 280-kilometre-long tourist route from the River Rhine to the mountains of the High Eifel. It links 39 sites within the Geopark Vulkanland Eifel in the Volcanic Eifel (Vulkaneifel), at which geological, cultural-historical and industrial-historical nature and cultural monuments on the subject of volcanicity in the Eifel are located.
The Vulkanland Eifel Geopark is a German national geopark in the Volcanic Eifel region that was established on 19 April 2005. Covering an area of 2,200 km², the geopark extends from the Belgian border in the west over the Eifel mountains to the River Rhine in the east. The countryside here which has been shaped by the volcanism of the past contains numerous maars, cinder cones, lava flows lava domes calderas and bubbling springs. The largest caldera was formed by the Laacher See volcano that last erupted about 13,000 years ago. A sign of continuing volcanic activity in this region are the volcanic gases that are still visibly being discharged into the atmosphere.
Hveravellir is a geothermal field of the Oddnýjarhnjúkur-Langjökull subglacial volcanic system in the north of Langjökull glacier.
