Everything you need to know about the Reykjanes Peninsula volcanoes
When the Fagradalsfjall eruption kicked off in March 2021, it captured the world’s attention. This little known volcano had slumbered on the Reykjanes Peninsula for centuries before waking up in dramatic style. For six months, and again briefly in 2022, magma rose to form restless lakes of lava which churned and overflowed. Fountains of molten rock exploded into the air and red hot rivers snaked down its flanks, altering the landscape for good. Visitors hurried to take a closer look, hiking up the valley ridge and flying over the scene in helicopters and small planes.
But Fagradalsfjall is not the only volcano in the region. On the Reykjanes Peninsula, there are a handful of volcanic systems, some more lively than others. A volcanic system is defined as a group of volcanoes that share the same magma chamber, in other words are fed from the same build up of magma below the surface. Elsewhere in Iceland, many volcanic systems take their name from a central volcano – as with Hekla or Katla. In the Reykjanes Peninsula, these systems don’t have as clear a focus so their name refers to a wider geothermal area. Here’s everything you need to know about the Reykjanes Peninsula volcanoes.
