Dimmuborgir

Lava bubbled and steamed when Dimmuborgir was born in a volcanic eruption in Lúdentsborgir and Þrengslaborgir about 2,000 years ago. This was the largest volcanic agglomerate eruption Mývatn has seen since the ice age. 

Dimmuborgir are located in a small valley. Experts say that when they were formed the molten agglomerates flowed into the depression, gradually filled it and became volcanic rock. What we are left with today is the unique landscape we know as Dimmuborgir.
