The session “Volcanic processes: Tectonics, Deformation and Geodesy” deals with the documentation and modelling of the tectonic, deformative 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, geophysical and geodetic measurements, and analytical, analogue, and numerical simulations. 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. Geodetic studies aim at detecting detailed and precise volcano deformation data, obtained mainly through GPS and InSAR, as well as at their modelling to imagine sources. The session includes, but is not restricted to, the following topics: • volcanism and regional tectonics; • formation of magma chambers, laccoliths, and other intrusions; • dyke ad sill propagation, emplacement, and arrest; • earthquakes and eruptions; • caldera collapse, resurgence, and unrest; • flank collapse; • volcano deformation monitoring; • volcano deformation and hazard mitigation.
