Iceland - Exploring the underground world
In Jule Verne's science fiction novel "A journey to the Centre of the Earth" an expedition descends into an Icelandic volcano. Science fiction or not, but Iceland's underground world can really be explored and what you find is truly remarkable. Iceland is a giant geological hotspot, located on the mid atlantic ridge. The country is one of the most active volcanic regions in the world. Everyone remembers the Eyjafjallajokull eruption in 2010. But there are also dormant volcanoes like Thrihnukagigur, shown here on the right. This volcano is unique, because its magma channel has drained after an eruption 4000 years ago. You can descent 120 meters in this cathedral-like volcano, which is an out-of-this-world experience. Volcanic eruptions also often result in the creation of lava tubes. Frozen water, dripping from cracks in the ceiling, creates beautiful ice stalactites, such as in the Lofthellir and Buri lava tubes. Buri also hosts a large frozen lava fall at the end of a 1 km long lava tube.
