Southern Peninsula

南半島の火山と山

Iceland's Peaks and Volcanoes

The Reykjanes Peninsula is a geologically active region where the Mid-Atlantic Ridge rises above sea level. This collection features the sites of recent basaltic eruptions at Fagradalsfjall and Litli-Hrútur alongside ancient shield volcanoes and hyaloclastite peaks. Highlights include the iconic cone of Keilir, formed during a subglacial eruption, and the Stampar crater row. These landmarks showcase Iceland’s volcanic evolution, from dormant craters like Eldborg to the expansive lava fields of the Krýsuvík system.
