Torfajokull volcanic area (about 190 km²) comprises the largest high
temperature area of the country (140 km²).
Standing on a good vantage point overlooking the whole area is
almost like sitting in a boat on a boiling and steaming, unstable and
The active fissure area is about 6 km wide and 31 km long.
This part of the country also comprises the largest rhyolite area
with various breccias, basaltic lava fields, alkaline lava fields,
hyaloclastites, tillite and rhyolitic craters.
Some of these formations can be traced to the latest warm and
cold epochs of the Ice Age.
highest peak of the relatively low, but carved and cut landscape, is
Haskerdingur (1,278 m) of the Kaldaklof Mountains.
In the proximity of Landmannalaugar rhyolitic rock is dominant
and the colours of the landscape are simply unbelievable.
Mt Blahnukur was created sub-glacially.
Mt Brennisteinsalda as well, but also during the latest warm
epoch and the rhyolitic crater in its slopes around the year 1480
as well as the lava field to the south of Lake
The volcanic activity during Holocene was mainly concentrated in
the western part of the Torfajokull Area between Mt Laufafell in the
south and the craters Stutur and Ljotipollur in the north.
The Veidivotn fissure system continues from there all the way to
the Bardarbunga Glacier Area.
eruptions in the Veidivotn Area around the year 150 AD have been
confirmed and at the same time similar eruptions near the crater
Hnausapollur on the Sigalda Road and the creation of the Domadalur Lava
Field (Domadalur Road).
The number of alkaline, rhyolitic lava fields in the Torfajokull
Area has not been confirmed, but they are considered to be 8-11.
two coloured ash layer from the early 10th century was
considered to be the product of the Torfajokull area, but the darker
part of it has now been traced to the so-called Vatnaoldur Craters near
Lakes Veidivotn and the light coloured, rhyolitic part from simultaneous
volcanic activity in the Torfajokull Area, when the Obsidian Lava Field
(Hrafntinnuhraun) was created.
The southernmost craters of the area are in the proximity of Mt
Laufafell, Lakes Skyggnisvotn and the so-called Midvegur Route.
