7-7-7-7-7-7-7-7-7-7-7-7-7-7 From: Eugenio Nicotra <eugenio.nicotra@xxxxxxxxx> Dear Colleagues, we would like to invite you to submit an abstract to our Session "V06 Geochemical and Geophysical Responses of Magma Feeding Systems and Eruption Dynamics at Active and Quiescent Volcanoes" at the next IUGG 2023 in Berlin (11-20 of July 2023). The deadline for abstract submission is on February 14th. Description This session aims at attracting inter-disciplinary studies that put together geochemical and geophysical data to investigate the architecture of magma feeding systems and the processes that occur before and during eruption. These processes and their time scales can significantly influence eruptive scenarios and therefore a better knowledge of them is key to strategically plan the actions needed to mitigate volcanic risk. An articulated network of magma reservoirs developing from mantle sources up to eruptive vents forms the architecture of a plumbing system. Here, magma differentiation, degassing, recharge and mixing act at different depths and across different geometries, depending on the physical and chemical properties of magmas and their crystal cargo. In this context, magma dynamics and volcano-tectonic events can both trigger eruptions. Particular focuses will be related to: i) geophysical and geochemical reconstructions of the architecture of volcano plumbing systems; ii) magma storage and ascent dynamics and their timescales; iii) magma differentiation/evolution processes; iv) pre- and syn-eruptive physical response of the system; v) reconstruction of eruptive scenarios from volcano-stratigraphy of deposits; vi) eruption triggers and vii) magma source processes The Conveners: Eugenio Nicotra (Università della Calabria, Italy) H.
