Volcanism witnesses every major change of our planet and other planets. In Advances in Volcanology, scientists from highly active volcanic countries, such as Japan, Italy, and New Zealand, as well as others from Germany, Portugal, and Russia, debate less commonplace themes. Topics from classic field volcanology, including practical problems with volcanic stratigraphy in oil exploitation, to the most modern techniques related to tomographic studies are discussed. The question about the role of hydro-volcanism as a modifying factor versus juvenile gases as the primary engine of volcanism is discussed in full
