Data Driven Imaging of volcanic Plumbing Systems
The project combines Volcanology, Petrology, numerical modelling and Statistics to tackle two of the great standing challenging in volcanology: 1. Forecasting the magnitude of future eruptions; 2. Forecasting the duration of Volcanic eruptions. Chemical data collected over the eruptive history of different volcanoes will be used to constrain numerical and statistical models to quantify the distribution of eruptible magma within the lithosphere. Once the workflow will be established the results will be applicable to any volcanic system globally. Given that 1500 volcanoes are currently active on Earth and about a billion people leave in their close proximity, this project will have a direct impact on our society.

Volatile cycling and magma degassing on Earth and Exoplanets: A window into the geodynamics of planetary bodies
The evolution of the Earth鈥檚 atmosphere has been shaped by magmatic degassing. In turn, the chemistry of magmatic gases is linked to the conditions of magma formation and therefore to geodynamic. Thus, linking the chemical evolution of the atmosphere to Earth鈥檚 geodynamic evolution would allow the study of exoplanets鈥� geology from the investigation of the chemistry of their atmospheres.
To achieve this target, we will measure the content of H2O, CO2, S, Cl and F as well as the oxidation state of S, in apatite inclusions in zircons with age spanning the entire geological history of our planet. Zircons serve both to date the apatites precisely and to avoid any chemical exchange with the exterior. These data will allow to establish which ratios of volatiles species in exoplanetary atmospheres can indicate if a magma ocean operated on the planet or if active plate tectonics is plausible.
This project will be realise within the framework of the "Center for the Life in the Universe" of the AV短视频 (/sciences/cvu/)
