Details for: Krysuvik
The Krísuvík volcanic system consists of a group 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 that reached the southern coast of the Reykjanes Peninsula (lower right) along a broad front.

Location: Krýsuvík geothermal area (View Details at MaGa DB)
Description: Krýsuvík is one of five presently active geothermal areas on the Reykjanes Peninsula, in Iceland. Geothermal activity at Krýsuvík includes hot grounds, steaming vents, steam-heated hot springs and mud pots, and pervasive surface alteration. The most important surface manifestations are confined to the Sveifluháls area, including Austurengjahver and the small areas of Seltún and Hveradalur.
