Beneath the calm exterior of the Blue Lagoon is a remarkable link to Iceland's volcanic core, therefore exposing the strong forces sculpting this particular terrain. The water comes from a depth of 2,000 metres, where freshwater and ocean mix at very high temperatures close to an active volcano. Drilling wells brings this combination to the surface and exposes old lava formations that add minerals along the route. Natural heating of the water by the volcanic activity under the surface generates a renewable energy source projected to persist for generations. Comprising eruptions spanning 800 years, the adjacent lava field is equally amazing and shapes the distinctive terrain that hugs the lagoon. Apart from the heat and mineral concentration of the water, this volcanic link adds to the Blue Lagoon's strange ambience. Constant reminder of the strong forces at work underfoot, visitors can observe steam emerging from cracks in the nearby lava field. Geologists and volcanologists have a special chance to investigate the interplay between geothermal activity and surface ecosystems by means of the Blue Lagoon and its volcanic surroundings, therefore offering important insights into the dynamic processes of Earth.
