Photo Gallery


The Reykjanes volcanic system at the SW tip of the Reykjanes Peninsula, where the Mid-Atlantic Ridge rises above sea level, comprises a broad area of postglacial crater rows and small shield volcanoes. Snow-covered Sandfellshæd shield volcano (lower center), capped by a small crater, rises only 74 m above the Atlantic Ocean to the south. Most of the volcanic system is covered by Holocene lava flows. Eruptions have occurred in historical time during the 13th century at several locations on the NE-SW-trending fissure system.

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 snow-mantled Reykjanes volcanic system forms the SW tip of the Reykjanes Peninsula, where the Mid-Atlantic Ridge rises above sea level. The Reykjanes volcanic system is the westernmost of a series of four closely spaced, NE-SW-trending en echelon fissure systems that extend diagonally across the Reykjanes Peninsula. Most of the Reykjanes volcanic system is covered by Holocene lavas, and eruptions have occurred in historical time during the 13th century at several locations.

The submarine Reykjaneshryggur volcanic system, lying off the SW tip of Iceland at the top of the photo, is part of the Mid-Atlantic Ridge, which extends onto the Reykjanes Peninsula in the foreground. Numerous submarine eruptions at Reykjaneshryggur dating back to the 12th century have been observed during historical time, some of which have formed ephemeral islands. Tephra deposits from earlier Holocene eruptions are preserved on the Reykjanes Peninsula in the foreground.
