Interaction between the different phases (exsolved and dissolved volatiles, liquid melt, crystals and pyroclasts) that separate during magma evolution, ascent and storage as a result of interlinked fluid, thermodynamic and chemical processes have a dramatic influence on eruption dynamics, resulting in a plethora of explosive eruptions types.
On one side, constraining volatile budget in magmas and quantifying degassing processes is a fundamental task to better understand the role of volatile elements on eruption dynamics. On the other side, the complex shallow plumbing system dynamics produces seismic and acoustic events, ground deformation and changes in the hydrothermal system often preceding or follow the explosive activity and direct field observations can constrain individual eruptive processes.
For this reason, the session aims at gathering field observation and experimental and modeling studies on eruptive processes to unlock the complex dynamics of volcanic activity. We hereby invite contributions focusing on (but not restricted to) volatiles in magmas, crystallization dynamics, effusive/explosive transition, rheology of gas-liquid-solid mixtures, fragmentation processes.
Further we like to stimulate discussion on how multidisciplinary approaches can be used to advance the interpretation of geochemical and petrological observations on magmatic products and more specifically on the quantification of disequilibria processes during volcanic eruptions.
