The Reykjanes volcanic system at the SW tip of the Reykjanes Peninsula in Iceland comprises a broad area of postglacial crater rows and small shield volcanoes. Snow-covered Sandfellshæd shield volcano (lower center), capped by a small crater of approximately 400 m diameter, rises less than 100 m above the Atlantic Ocean to the south (background). Most of the volcanic system is covered by Holocene lava flows. Eruptions have occurred in historical time. Eruptions during the 13th century distributed tephra across the Reykjanes peninsula and lava covered about 50 km2.
