Recent eruptions and unrest of different volcanoes worldwide have highlighted the importance of dedicated monitoring activities. Geochemical monitoring of fluids from active volcano-hydrothermal systems, coupled with geophysical measurements and basic volcanological investigations, indeed provides essential information to forecast eruptions.
Volcano-hydrothermal systems are expressed as subaerial, submarine or sublacustrine fluid discharges, as fumaroles, springs. These “wet systems” are prone to phreatic eruptive activity that can occasionally escalate into phreatomagmatic of even magmatic eruptions.
In this session we welcome contributions aimed at (1) geochemical measurement techniques and data processing to elaborate conceptual previsional models, (2) the development of new approaches for the investigation gas-water-rock interactions inside subaerial of submarine volcano-hydrothermal systems, (3) understanding ocean acidification and climate change processes or energy sources for chemolithotrophic ecosystems.
