FagradalsfjallReykjanes Peninsula
A volcanic system on Reykjanes, with landscapes shaped by recent lava flows.
Fagri dalur means “beautiful valley”; fjall is mountain: the mountain of the beautiful valley.
In spring 2010, activity began at the pass between the glaciers before moving to the ice-covered main volcano. The different stages produced lava, volcanic ash and meltwater floods, leaving distinct traces in the surrounding landscape.

Icelandic Met Office · Reykjanes activity overviewA series of fissure eruptions began along the Sundhnúkur crater row in December 2023. Individual events have different dates and extents; the start of the sequence does not mean that eruption continued without interruption afterwards.
