Shield volcanoes of Iceland

Situated in the Ódáðahraun lava field, Trölladyngja () is the biggest of the Icelandic shield volcanoes, reaching a height of above sea level, and rising almost above the surrounding desert and lava fields. It part of the Bárðarbunga volcanic system and has a volume of with some extensive lava flows to the north of Bárðarbunga.

Skjaldbreiður (, "broad shield") is an Icelandic lava shield formed in a huge and quite protracted eruption series from about roughly 9,500 years ago. The extensive lava fields which were produced by this eruption, flowed southwards, and formed the basin of Þingvallavatn, Iceland's largest lake, and Þingvellir, the "Parliament Plains" where the Icelandic national assembly, the Alþing was founded in 930.

Theistareykjarbunga (Þeistareykjarbunga, ) is a shield volcano in north-eastern Iceland with two fissure vents called Þeistareykjahraun and Borgahraun , and two cones: the Stórahversmór and the , Stóravíti . They both are currently extinct, although there is evidence suggesting the potential for activity such as recent localised uplift and seismicity. The multiple vents make up the Theistareykir (Þeistareykir) volcanic system, with more recent evidence that the former classification as a shield volcano is better considered an embryonic central volcano with associated fissure swarm, as rhyolite

Kollóttadyngja () is a shield volcano in the Ódáðahraun lava-field in Iceland. Its height reaches 1,177 metres, and it has a diameter of 6–7 km. The summit crater is 800 metres in diameter, but only about 20–30 metres deep. In its centre, there is a bowl about 150 metres in diameter with a depth of about 60–70 metres.
