Photo Gallery


The two westernmost of five NE-SW-trending volcanic systems on the Reykjanes Peninsula cut diagonally across this aerial photo. The Reykjanes volcanic system, which lies near the SW tip of the peninsula, where the Mid Atlantic Ridge rises above sea level, has produced Holocene lava fields that extend to the western and southern coasts. The Krísuvík volcanic system, on the right side of the photo, has produced several eruptions since the settlement of Iceland. The latest of these took place during the 14th century.

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.
