Askja Caldera


Head into the Dyngjufjöll Mountains, to the north of Vatnajökull glacier, and you will find Askja, a massive caldera and volcano. The bedrock of the caldera sits atop a cavernous magma chamber that is still in the making. This was a volcano that essentially went unnoticed and unexplored until the 19th century. Scientists became interested in Askja after it unleased a number of eruptions between 1874 and 1875, with a particularly huge one coming in March of 1875. When that one hit, Askja spewed out w billion cubic meters of ash and pumice, forming a new caldera inside the old one in the process. In the years that followed, water filled the new caldera, which is where you will now find the 11km² Lake Öskjuvatn. This lake goes down 220m, making it one of the deepest in Iceland. There were a few more eruptions during the 1920’s, but nothing since the fall of 1961.

By Super Jeep:

This is a once in a lifetime experience that has to be seen to be believed. You will be riding in a Super Jeep across terrain that NASA once used to train astronauts. In the middle ages, this land was occupied by Icelandic outlaws. This is our favorite way to see Askja.!askja-super-jeep/cno2

– Jump into the warm milky-blue geothermal waters inside the Viti crater.

– German scientists Walter von Knebel and Max Rudloff visited Askja to study there in the early 1900’s, and now have a monument dedicated to them there.

– The tephra lava flowm from 1961, known here as “Vikrahraun,” can be visited. The lava is so light it floats on water.
