Hidden dynamics shaping magma mobility and eruptive style

On Tuesday, April 15, 2025, at 4:30 PM in Aula Arduino, the Department will host Fabio Arzilli from the University of Camerino for a seminar exploring the magmatic processes that precede and influence basaltic eruptions.

Basaltic eruptions are among the most widespread on Earth and other planetary bodies. They are driven by processes such as crystallization and vesiculation occurring in magma reservoirs and conduits beneath volcanoes. Understanding how these mechanisms affect magma mobility and eruptive style remains challenging, especially since they occur out of sight.

In his talk, Arzilli will present 4D experimental data on trachybasaltic magmas, observed in real time under high-temperature and high-pressure conditions. These experiments track crystal and bubble growth, offering new insights into magma viscosity and mobility within the Earth’s crust. Combined with numerical modeling, the results shed light on how dendritic crystallization can influence magma ascent and help determine the style of eruption.

An opportunity to dive into the core of volcanic dynamics, with a fresh perspective on magma physics.
