Launched last week, “Inside The Volcano” may sound like a ride at Alton Towers, but it is instead a very literal description of the dormant chamber of Thrihnukagigur, a volcanic peak just outside Reykjavik, which is now open to visitors. For the first time, intrepid travellers can climb over the rim and descend into the once-fiery abyss.
It has been 4,000 years since Thrihnukagigur last popped, and like all eruptions it was tremendously violent. Crucially, though, it wasn’t so cataclysmic as to destroy the chamber and the entire mountain; instead the vast geological pressure was likely to have been vented through tunnels and arteries deeper in the earth, preserving a newly opened chamber and creating what cave explorer Arni Stefánsson describes as a “pristine collapse”.
