Understanding and monitoring the phenomena associated with the Caldera unrest is of crucial importance for predict their future behavior, both for scientific purposes and for risk assessment. This multidisciplinary session is focused at the experimental and theoretical aspects of the studies related to the caldera dynamics in their unrest state. Contributes from seismology, ground deformation, gravimetry, geochemistry, volcanology, theoretical modeling and numerical simulations are welcome. Presenters should enlighten in their talk or posters the multidisciplinary aspects of their work, focusing at the contribution of their specific observation/experiment/model/simulation to the general aspect of caldera unrest. Talks describing the results of multidisciplinary scientific projects on the caldera unrest problems are particularly solicited.
