Magmatic and volcanic processes are being increasingly unveiled as long as theoretical models, numerical codes, and advanced experiments are developed and applied to a variety of test cases and conditions. Several aspects concerning the chemical and physical state and evolution of magmas before, during and after eruptions can now be understood, and complex processes can be described and predicted. At the same time, as long as our knowledge improves, new challenges emerge, requiring more sophisticated approaches and instruments. This session invites contributions focusing on advancements in experimental, theoretical, and numerical work aimed at describing any aspect of the complex processes characterizing magma evolution and eruption dynamics, including, but not restricted to, the followings: multicomponent chemical equilibria and kinetics, complex magma rheology, deep magma dynamics, magma chamber formation and dynamics, separation and dynamics of the gas phase, geothermal system chemistry and dynamics, crack formation and dyke injection, magma-rock interaction â€“ either chemical or mechanical, magma ascent and fragmentation, volcanic conduit and vent dynamics, dynamics of lava fountains, strombolian eruptions, supersonic jets and volcanic plumes, generation and dynamics of lava flows and pyroclastic flows, etc. Constraints given to the above processes through a variety of techniques including analysis and inversion of geochemical and geophysical signals, analytical work on the eruption products, etc. are encouraged. Contributions either dealing with specific cases or presenting the results of parametric studies are welcome.
