Data from the Global Volcanism Program of the Smithsonian Institution
Details for: Krysuvik-Trolladyngja
The Krýsuvík-Trölladyngja volcanic system consists of NE-SW-trending crater rows and small shield volcanoes cutting the central Reykjanes Peninsula west of Kleifarvatn lake (top center). Several eruptions have taken place since the settlement of Iceland, including the emplacement of a large lava flow from the Ogmundargigar crater row around the 12th century. The lava flow was confined to the valley between the two parallel ridges (top left), before reaching the southern coast of the Reykjanes Peninsula (lower right) along a broad front.

The Krýsuvík-Trölladyngja volcanic system is described by the Catalogue of Icelandic Volcanoes as an approximately 50-km-long composite fissure swarm trending about N38°E, including a 30-km-long swarm of fissures, with no central volcano. It is one of the volcanic systems arranged en-echelon along the Reykjanes Peninsula west of Kleifarvatn lake. The Fagradalsfjall and Krýsuvík fissure swarms are considered splits or secondary swarms of the Krýsuvík–Trölladyngja volcanic system. Small shield volcanoes have produced a large portion of the erupted volume within the system. Several eruptions have taken place since the settlement of Iceland, including the eruption of a large basaltic lava flow from the Ogmundargigar crater row around the 12th century. The latest eruption, identified through tephrochronology, took place during the 14th century.
