Volcano Calendar 2016
: We're proud to present our new volcano calendar 2016: 13 different and attractive images of volcanoes, volcanic landscapes and phenomena taken during volcano tours over the past few years.
Types of tours
: We offer a broad variety of tours to volcanic areas: volcano expeditions and specials, discovery tours with hiking, photography, nature and culture, pilot tours and private custom tours.
: A third tectonic setting where volcanism occurs is believed to be the result of mantle plumes and not directly related to plate boundaries. So called hot spot volcanoes fall into this category.
