Background:

Clark submarine volcano lies near the southern end of the Southern Kermadec arc. This basaltic and dacitic stratovolcano consists of a basal substrate of massive lava flows, pillow lavas, and pillow tubes overlain by volcaniclastic sediments. Craters occupy the complex crest of the volcano. Clark is the southernmost volcano of the submarine chain that displays hydrothermal activity. Diffuse hydrothermal venting and sulfide chimneys were observed near the summit of Clark volcano during a New Zealand-American NOAA Vents Program expedition in 2006.

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.
Volcanoes outside Earth
Volcanoes in the Solar System: The Earth is not the only place with volcanic activity. Active volcanism also occurs at at least 3 other bodies in our Solar System.
