Episode 3: FROM LAKE MÝVATN TO VATNAJÖKULL
Fire Beneath the Ice
The third episode focuses on northern and eastern Iceland, regions where volcanic activity and the action of major glaciers have interacted with particular intensity. The Mývatn area is one of the most active volcanic systems in the country, with craters, cones and extensive lava fields formed by fissure eruptions and subglacial volcanism. At Skútustaðir, pseudocraters bear witness to the explosive contact between magma and water-saturated sediments, while at Grjótagjá and in the geothermal areas of Námafjall, Hverir and Leirhnjúkur, fractures in the crust allow heat and hydrothermal fluids to rise to the surface. The Hverfjall cone and the chaotic formations of Dimmuborgir reflect different eruptive phases of this system, ranging from hydromagmatic explosions to lava flows that solidified to form arches, towers and cavities. Farther north, powerful glacial rivers give rise to spectacular waterfalls such as Dettifoss and carve canyons and striking landforms in places like Hljóðaklettar and the natural amphitheatre of Ásbyrgi.
