P83. Multidisciplinary investigations of volcano-tectonic processes

Volcanoes are characterized by several processes occurring at different spatial and temporal scales. The tectonic setting may control the occurrence of volcanism, as well as the storage of the magma at depth, its migration, the eventual uprise to the surface and volcano morphology. Deformation structures may form and interact during tectonic and volcanic activity, accommodating the deformation caused by tectonic stress, magma migration, pressure variations in the hydrothermal system, volcanic eruptions, and magma chamber withdrawal. Processes such as caldera collapse may control the subsequent eruptive vent distribution, hydrothermal fluid circulation and deformation pattern during volcanic unrest. For these reasons, studying the mechanisms linking active volcano-tectonic processes to magmatic and hydrothermal fluids circulation may improve the understanding of active volcanic systems with implications for assessing volcanic hazard, volcano monitoring and geothermal system characterization. Hence, we encourage the submission of studies relying on results from fieldwork, ground-based geophysical and geochemical methods, remote-sensing and laboratory studies (e.g., analogue modelling) that can help shed light on such non-trivial relationships between tectonic/volcano-tectonic deformation and magmatic/hydrothermal and processes. This session aims to illustrate the recent studies and advancement in understanding such processes studies combining different disciplines are welcome.
