Volcanic Groups
A volcanic group, depending on context, is either (1) a group of related volcanoes in the form of volcanic fields, complex volcano, volcanic complexes and volcanic cone, cone clusters, or (2) a stratigraphy, stratigraphic group (stratigraphy), group consisting of volcano, volcanic stratum, strata.

Volcanic Field
A volcanic field is an area of Earth's Earth's crust, crust that is prone to localized volcano, volcanic activity. The type and number of volcanoes required to be called a "field" is not well-defined. Volcanic fields usually consist of clusters of up to 100 volcanoes such as cinder cones. Lava flows may also occur. They may occur as a monogenetic volcanic field or a polygenetic volcanic field. Description Alexander von Humboldt observed in 1823 that geologically young volcanoes are not distributed uniformly across the Earth's surface, but tend to be clustered into specific regions. Young volcanoes are rarely found within cratons, but are characteristic of subduction zones, rift zones, or in ocean basins. Intraplate volcanoes are clustered along hotspot (geology), hotspot traces. Within regions of volcanic activity, volcanic fields are clusters of volcanoes that share a common magma source. Unlike a large volcano with satellite or subsidiary vents, a volcanic field's vents have ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Daisetsuzan Volcanic Group

Mount Edziza Volcanic Complex
The Mount Edziza volcanic complex ( ; abbreviated MEVC) is a group of volcanoes and associated lava flows in northwestern British Columbia, Canada. Located on the Tahltan Highland, it is southeast of Telegraph Creek and southwest of Dease Lake. The complex encompasses a broad, steep-sided lava plateau that extends over . Its highest summit is in elevation, making the MEVC the highest of four large complexes in an extensive north–south trending volcanic region. It is obscured by an ice cap characterized by several Glacier morphology#Outlet glaciers, outlet glaciers that stretch out to lower altitudes. The MEVC consists of several types of volcanoes, including stratovolcanoes, shield volcanoes, cinder cones and lava domes. These volcanoes have formed over the last 7.5 million years during five cycles of magmatic activity which spanned four geologic epochs. Volcanic eruptions during these magmatic cycles produced a wide variety of volcanic rocks that comprise 13 geol ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Monti Della Tolfa
The Monti della Tolfa (or Tolfa Mountains) are a volcanic group in the Anti-Apennines of the northern part of the Lazio region of Central Italy. They are bounded by the Tyrrhenian Sea coast to the west, by the Monti Sabatini to the east, and by the Monti Cimini and the Mignone river to the north. Tolfa and Allumiere are the principal towns. The highest peak is the Monte Maggiore (633 m above sea level). The Monti della Tolfa consists mostly of trachytes formed during the Eocene and the early Pleistocene. The mountains are an important source of alunite, from which alum An alum () is a type of chemical compound, usually a hydrated double salt, double sulfate salt (chemistry), salt of aluminium with the general chemical formula, formula , such that is a valence (chemistry), monovalent cation such as potassium ... is extracted.

Milbanke Sound Group
The Milbanke Sound Group, also called the Milbanke Sound Cones, is an enigmatic group of five small basaltic volcanoes in the Kitimat Ranges of the Coast Mountains in British Columbia, Canada. Named for Milbanke Sound, this volcanic group straddles on at least four small islands (three of which are uninhabited), including Swindle, Price, Lady Douglas and Lake Island. Not much is known about this group of volcanoes and they remain undated. However, they all likely formed in the past 10,000 years after the last glacial period as evidenced by a small amount of erosion. The age of the most recent volcanic activity is also unknown. Most of the Milbanke Sound Cones are covered by mature forest. Kitasu Hill and Helmet Peak are the only two cones that are officially named. This group of volcanoes is unlike many other volcanic groups in Canada as it resides on islands instead of on the mainland. The volcanoes form a northwest–southeast trend along the British Columbia Coast. To the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Mount Meager Massif
The Mount Meager massif is a group of volcanic peaks in the of the Coast Mountains in southwestern British Columbia, Canada. Part of the Cascade Volcanic Arc of western North America, it is located north of Vancouver at the northern end of the Pemberton Valley and reaches a maximum elevation of . The massif is capped by several eroded volcanic edifices, including , volcanic plugs and overlapping piles of lava flows; these form at least six major summits including Mount Meager which is the second highest of the massif. The Garibaldi Volcanic Belt (GVB) has a long history of eruptions and poses a threat to the surrounding region. Any volcanic hazard ranging from landslides to eruptions could pose a significant risk to humans and wildlife. Although the massif has not erupted for more than 2,000 years, it could produce a major eruption; if this were to happen, relief efforts would be quickly organized. Teams such as the Interagency Volcanic Event Notification Plan (IVENP) are ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Karpinsky Group
The Karpinsky Group () is a volcanic group located at the southern end of Paramushir Island, Kuril Islands, Russia. The group is capped by two gently sloping cones rising to a height of 1,326 m. They are composed of andesites and andesite-basalts. In the two craters there are fumaroles and fountains of liquid sulfur. The last major, and only historic, eruption was in 1952. The sides of the volcanoes have been heavily glaciated leaving a number of cirques which were initially thought to be eroded craters. The volcanoes were named after the geologist Aleksandr Petrovich Karpinsky.

Kaiserstuhl (Baden-Württemberg)
The Kaiserstuhl (, "Emperor’s Chair") is a range of hills in the state of Baden-Württemberg in southwest Germany with a maximum height of . It is of volcanic origin and located in the southwest of the state in the Districts of Germany, counties of Emmendingen (district), Emmendingen and Breisgau-Hochschwarzwald. In terms of Natural regions of Germany, natural regions it is considered to be a part of the Upper Rhine Plain. Name The name "Kaiserstuhl" is believed to refer to King Otto III, Holy Roman Emperor, Otto III, who held court near Sasbach am Kaiserstuhl, Sasbach on 22 December 994. From then on, the whole hill range was called the Königsstuhl – the King's Chair. In May 996, Otto III was crowned Emperor and the King's Chair eventually became the Emperor's Chair – "Kaiserstuhl". Reliable sources mention the name Kaiserstuhl only as early as 1304 and historians thus suppose that the term Kaiserstuhl was not coined until the 13th century. Geography Location The Ka ...

Jemez Mountains
The Jemez Mountains (, Tewa: ''Tsąmpiye'ip'įn'', Navajo: ''Dził Łizhinii'') are a group of mountains in Rio Arriba, Sandoval, and Los Alamos counties, New Mexico, United States. Numerous Puebloan Indian tribes have lived in the Jemez Mountains region for centuries before the Spanish arrived in New Mexico. The Pueblo Nations of this region are the Towa-speaking Jemez people, after whom the mountain range is named, and the Keres-speaking Zia People. Pueblos in the Jemez Mountains of New Mexico consisted of compact multistoried buildings which enclosed small plazas. Most of their several hundred rooms were probably occupied by single families, but some were storerooms. The Jemez Mountains include climates varying from desert at the lowest elevations to sub-arctic conditions at the highest elevations. A significant diversity of climate and vegetation is linked to gradients in elevation and the region's topographical features. The highest point in the range is Chicoma Moun ...

Gambier Group
The Gambier Group is an Early Cretaceous aged geologic group in the southern Coast Mountains of British Columbia, Canada. It was formed on the easternmost point of the Wrangellia Terrane as a volcanic arc about 100 million years ago along a west-to southwest-dipping subduction zone. This prehistoric volcanic arc is generally referred to as the Gambier arc or Gambier volcanic arc.
