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 ...
The Reykjanes and the Svartsengi volcanic systems are sometimes classified together under the former name. 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.
It belongs to the Askja volcanic system or the volcanic system, (sometimes called the (Dyngjufjöll volcanic system), and is part of the Vatnajökull National Park. The central volcano of basalt and rhyolite has its own system of crevices and fissures, which last erupted in 1961. (Part of the North volcanic zone (NVZ)).
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 ...
It part of the Bárðarbunga volcanic system and has a volume of 15 km 3 (3.6 cu mi) with some extensive lava flows to the north of Bárðarbunga. [ 4 ] It is about 10 km (6.2 mi)in diameter and its inclination is 4 to 5° in the lower slopes, but 6 to 8° at higher elevations. [ 5 ]

During the two weeks of eruption, volcanic activity thawed no less than 3 km 3 (0.72 cu mi) of ice, and this continued to a lesser extent for some time after the end of the eruption. [ 6 ] The newly formed tindar disappeared again completely under the glacier ice about 1 year later, [ 6 ] but an identifiable ice cauldron remained until at least ...
