Kilauea volcano photos: The most active volcano in the world with a record long lasting eruption since 1983: images of lava flows, lava lakes, explosions, lava meeting the ocean, aerials and more.
Volcanoes & Earthquakes: Look up active volcanoes and earthquakes worldwide on our web-app, featuring an interactive map you can embed on your website or use as stand-alone tool.
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.
