Tours to erupting volcanoes
: From time to time, we organize special tours to see volcanoes in eruption. These are often announced only few days or weeks in advance. Find out more!
Divergent plate boundaries in oceans
: Two ocean plates move apart from each other. Hot upwelling mantle material forms magmas that continuously produce new oceanic crust. An ocean widens.
