Situated in the Ódáðahraun lava field, Trölladyngja (Icelandic pronunciation: [ˈtʰrœtlaˌtiɲca] (
listen)) is the biggest of the Icelandic shield volcanoes, reaching a height of 1,468 metres (4,816 ft) above sea level,[1] and rising almost 600 metres above the surrounding desert and lava fields.
It is about 10 kilometres in diameter and its inclination is 4 to 5° in the lower slopes, but 6 to 8° at higher elevations. Its oblong crater is about 1,200 to 1,500 metres in length, 500 metres broad, and about 100 metres deep.
Most of its lava fields have flowed in a northerly direction, with one branch of it reaching the valley of Bárðardalur, a distance of roughly 100 km.
Reports of an eruption in 1961 at Trölladyngja are most likely attributed to nearby Askja Caldera, which erupted the same year.[1][2]
