The mountain Fagradalsfjall is a volcano in areas of eruptive fissures, cones and lava fields also named Fagradalsfjall. [21] The Fagradalsfjall fissure swarm was considered in some publications to be a branch or a secondary part of the Krýsuvík-Trölladyngja volcanic system on the Reykjanes Peninsula in southwest Iceland, [22] [23] but scientists now consider Fagradalsfjall to be a separate ...
Accordingly, volcanoes such as Þorbjörn have been assigned by authors to either name. [15] Fagradalsfjall: RVB: Langhóll, Fagradalshraun, Geldingadalir: nil: Fissure swarm with effusive lava flows. Crater rows with spatter, scoria and some tuff cones, tindars and hyaloclastite hills. [47]
Hofsjökull, subglacial volcano is a shield type with caldera, formed during the Last Glacial Period. The Hofsjökull glacier is the third largest ice cap after Vatnajökull and Langjökull. The largest active volcano in the country, situated in the west of the Highlands [32] [33] See chronology below: Hofsjökull 2,500,000-11,000, Hofsjökull 2015
The eruption is near Fagradalsfjall mountain, and Icelandic Wikipedia therefore has an article is:Eldgosið við Fagradalsfjall 2021 about the eruption (translated "Eruption at Fagradalsfjall 2021"). The eruption itself, however, is in a valley called Geldingadalur (singular) or Geldingadalir (plural); it's not Fagradalsfjall itself which is ...
Situated in the Ódáðahraun lava field, Trölladyngja (Icelandic pronunciation: [ˈtʰrœtlaˌtiɲca] ⓘ) is the biggest of the Icelandic shield volcanoes, [3] reaching a height of 1,460 metres (4,790 ft) above sea level, and rising almost 600 m (2,000 ft) above the surrounding desert and lava fields. [1]
Other shading shows: calderas, central volcanoes and fissure swarms, subglacial terrain above 1,100 m (3,600 ft), and seismically active areas. Clicking on the image enlarges to full window and enables mouse-over with more detail.
And the tuff cone from Victoria Land, Antarctica, is placed next to known granitic plutonic complexes and seems to be a parasitic cone of a stratovolcano, whereas Keilir is located adjacent to presently active volcanic systems and looks as if it were placed on top of the shield volcano Þráinskjöldur, though the last one is younger than the ...
The seismological study sees a parallel to the 2014–2015 eruptions and to the caldera drop in Bárðarbunga central volcano in that eruption, and postulate a similar magma migration to the eruption site though on a smaller scale. This could mean that the volcano is part of the fissure system of Bárðarbunga, not Grímsvötn. [8]
