Activity

Research activity

The research is oriented to the acquisition and processing of petrological, geochemical and geophysical data on active volcanoes in geodynamic contexts. Particular attention is given to the study of single volcanoes based on data acquired directly on the ground, from satellite and in the laboratory. The study of single eruptive events occurs both on the basis of direct and instrumental observations (monitoring of the isotopes of the radon offspring and other gases, soil and satellite thermal analyzes, soil measurements on the geometry of eruptive bodies and lava flows).
Part of the research activity focuses on the petrographic and minerochemical determination of the equilibrium paragenesis present in the collected samples (lavas, xenoliths, veins, comagmatic nodules, etc.) and interpreted in synductive or post-eruptive contexts. The acquisition of compositional data allows the estimation of P-T regimes linked to the crystallization of magmas, the latter correlated with the depths that accompanied the crystallization processes in the pre-eruptive phase. The geochemical modeling allows to reconstruct the dynamics inside the magma chamber, which can be decoded through the intersection with the geophysical data. Several studies are currently underway on Italian and foreign volcanoes. Thesis students are given the opportunity to develop independent projects on individual volcanoes.

(a)The Miravalles volcano in the homonymous caldera. (b) The Nakadake cone in the Aso caldera. (c) Stromboli's lava flow of August 2014 and (d) structural scheme of the feeding system.

Research targets:

The objective of this research is to apply a multidisciplinary approach to the study and monitoring of volcanic systems. This includes the integration of data from terrain, from satellite, from laboratory analysis and modelling aimed at improving our knowledge of the eruptive dynamics.
