Santorini Island, Greece, spring 2019: hike from Fira to Oia along the caldera
Another excursion during the geologic walking tour is the 12 km hike from Fira to Oia, a classic walk considered one of the best and most scenic hikes in the world and one of particular geologic interest as well. It leads through the elegant streets of Fira, Firostefani, Imerovigli and Oia as well as old mule paths, and for most of the time offers breathtaking views over the northern caldera of Santorini, which was the site where the violent Minoan volcanic eruption around 1600 BC took place and reshaped the island forever.

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.
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.
