- Project Title
- A new look into explosive volcanic eruption: integrated shock-tube experiments, field- and laboratory-based high-speed imaging and textural characterisation of pyroclasts
- Project Description
The aim of my current VERTIGO project is about the fragmentation process inside a volcano and the ejection dynamics of the gas-pyroclast mixture which are the closest witnesses of syn-eruptive processes. As the fragmentation process is beyond direct observation, we need to constrain other roads to increase our understanding of explosively erupting volcanoes and mitigate the associated hazards. So I will observe erupting volcanoes and laboratory experiments with high-speed video cameras and acoustic arrays, sample proximal deposits, analyze shock-tube experiments (fragmentation bomb) to quantify the influence of sample and experimental parameters, describe the textural properties of samples from field and experiments and model the particle ejection computationally.

- About me
I obtained my Bachelor degree at Università degli Studi Milano-Bicocca, Italy, in Geological Sciences and Technologies, with a project focused on the stratigraphy of Permiam volcanic rocks in Valganna, Varese, Italy. Later I got the opportunity to attend a double Master degree program Atlantis-INVOGE with focus on volcanology and geotechniques. This program allowed me to attend my first Master year at Università degli Studi Milano-Bicocca, Italy, and my second year at Michigan Technological University, Houghton, USA. My Master project focused on the textural characterization of volcanic ash from Pacaya Volcano, Guatemala. I have also done part of the work at the Laboratoire Magmas et Volcans, Clermont-Ferrand, France thanks to Erasmus funding.
