At the brand new "state-of-the-art" Lava Centre you will learn about the birth and growth of Iceland as one of the world�s largest volcanic islands. It has risen during millions of years from the submarine North Atlantic Ridge, through countless volcanic eruptions. They occur as a large mantle plume locally adds molten rock to the magma up-flow beneath the rifting segments that line this ridge. The spreading along the ridge results in the Eurasian and North American tectonic plates moving apart 20 kilometres every million years.
