A description of the session is provided below. We look forward to meeting at EGU! Valerio Acocella, Thorbjorg Agustsdottir, Agust Gudmundsson, Michael Heap, Sigurjon Jonsson, Virginie Pinel *GMPV8.1: Volcanic processes: tectonics, deformation, geodesy, unrest* The session deals with the documentation and modelling of the tectonic, deformation and geodetic features of any type of volcanic area, on Earth and in the Solar System. The focus is on advancing our understanding on any type of deformation of active and non-active volcanoes, on the associated behaviours, and the implications for hazards. We welcome contributions based on results from fieldwork, remote-sensing studies, geodetic and geophysical measurements, analytical, analogue and numerical simulations, and laboratory studies of volcanic rocks. Studies may be focused at the regional scale, investigating the tectonic setting responsible for and controlling volcanic activity, both along divergent and convergent plate boundaries, as well in intraplate settings. At a more local scale, all types of surface deformation in volcanic areas are of interest, such as elastic inflation and deflation, or anelastic processes, including caldera and flank collapses. Deeper, sub-volcanic deformation studies, concerning the emplacement of intrusions, as sills, dikes and laccoliths, are most welcome. We also particularly welcome monitoring data aimed at understanding magmatic processes during volcano unrest. These include geodetic studies obtained through GPS and InSAR, and their modelling to imagine sources, as well as geophysical and geochemical studies. The session includes, but is not restricted to, the following topics: â?¢ volcanism and regional tectonics; â?¢ formation of magma chambers, laccoliths, and other intrusions; â?¢ dyke and sill propagation, emplacement, and arrest; â?¢ earthquakes and eruptions; â?¢ caldera collapse, resurgence, and unrest; â?¢ flank collapse; â?¢ volcano deformation monitoring; â?¢ volcano deformation and hazard mitigation; â?¢ volcano unrest; â?¢ mechanical properties of rocks in volcanic areas.
