2-2-2-2-2-2-2-2-2-2-2-2-2 From: laura pioli <nuraxi2002@xxxxxxxx> Dear colleagues, Please consider submitting a contribution to the WRI/IAGC conference, held in Cagliari -Italy, (https://www.unica-wri-18.it <https://urldefense.com/v3/__https://www.unica-wri-18.it__;!!IKRxdwAv5BmarQ!butMC77YYC_7jvk8kxshG3reaxtgrssu0YnqHpmg98LMsjwwwUtpy82dCv1Zrqg9NWlb6HvZNKPI-udt4giyuge_3A$>) 16-21 June 2024 : *Geothermal systems and volcanism: from hazard assessment to geothermal resources* Hydrothermal and geothermal systems in active volcanic areas are rarely in steady state. Significant short-wavelength changes typically occur at short (days to months) timescales overprinting long-term (years) system evolution across the entire plumbing system of the volcanic setting. Such changes are often triggered by tectonic stress variations and can herald volcano unrest, changing the thermodynamic state of the system, affecting composition of fluids, rock permeability and fracture network, and ultimately cause volcanic hazard. In parallel, climate change imposes an energetic transition causing hydrothermal and geothermal systems to be investigated for the extraction of geothermal energy. Surface manifestations allow direct monitoring of geochemical and temperature parameters which are key data to assess magmatic vs. phreatic sources and the thermodynamic state of the system. Geophysical studies instead, provide a picture of the current state of the hydraulic system and are a useful tool to forecast its temporal evolution. A full geological characterization of hydrothermal systems allows gathering information on fluid flow, permeability distribution in fractured domains and the caprocks, and the stress system. Numerical simulations help in understanding and characterizing rock-fluid interaction processes and the geophysical observations associated with them. This session promotes discussions on the state of the art and recent advances on the knowledge and strategy to characterize hydrothermal systems at active volcanoes, and their potential use. We welcome studies aimed at characterizing and understanding the dynamics and peculiarity of these systems and their evolution through time. New approaches for the comprehensive interpretation of 4D multidisciplinary datasets are a key asset to promote future exploration, monitor hydrothermal fluids and hazard assessments associated with phreatic explosions, gas emission and volcano reactivation. The session is chaired by M. Lupi (University of Geneva), A. Mazzini (University of Oslo), L. Pioli (University of Cagliari). youâ??ll find instructions for abstract submission at https://www.unica-wri-18.it/registration-abstract-submission/ <https://urldefense.com/v3/__https://www.unica-wri-18.it/registration-abstract-submission/__;!!IKRxdwAv5BmarQ!butMC77YYC_7jvk8kxshG3reaxtgrssu0YnqHpmg98LMsjwwwUtpy82dCv1Zrqg9NWlb6HvZNKPI-udt4ghE55eIKA$> . *Deadline is on December 31, 2024.* Geothermal systems and volcanism: from hazard assessment to geothermal resources Hydrothermal and geothermal systems in active volcanic areas are rarely in steady state.
