Volcano Special Tours
: We organize tours to particularly active volcanoes and during ongoing eruptions for extended observation time from various viewpoints. These trips, exclusively for very small groups, are often announced only at short notice and require fast travel and flexibility. Each trip is accompanied by a volcanologist from our team. Examples include: Kilauea (Hawai'i), Colima (Mexico), Krakatau and many others.
Ambrym volcano photos
: Ambrym (Vanuatu) is one of the most active volcanoes in the world. Its vast caldera has an amazing moonscape and several active vents that contain boiling lava lakes, most famous Marum and Benbow.
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.
