Structure and dynamics of hydrothermal systems
Hydrothermal systems are found at most active volcanoes and their understanding is important for following reasons : Variations in hydrothermal circulation reflect the temporal evolution of the volcanic activity like the reactivation of the magmatic processes or preparation of the volcanic crisis ; Hydrothermal systems may interact with magma ascent leading to explosive hydro-magmatic eruptions ; Their emplacement and geometry are controlled by principal geological structures, therefore (…)
