(b) Pre-eruptive volcano physics

Cartoon showing the expected orientation of magma pathways in different volcanic setting, such as a caldera or a monogenetic field (see Corbi et al., 2015, Rivalta et al., 2019). *(2.1, GFZ)*

Cartoon showing the propagation path of the 2000 Miyakejima dike, which started below Miyakejima volcano and became arrested when hitting against a major fault system on its path, modifying the observed earthquake statistics (see Maccaferri et al., 2016 and Passarelli et al., 2015). *(2.1, GFZ)*

The team pre-eruptive volcano physics develops process-oriented analytical, numerical and analog models for the propagation and storage of magma and other fluids in the Earth’s crust. We simulate magma propagation focusing on the effect of rock rheology and stress heterogeneities induced for example by evolving surface loads in the context of extensional or compressional tectonics and stress interaction with pre-existing tectonic structures. We validate our models by looking at the shape, trajectory and velocity of the dikes, crustal deformation, seismicity rates, scaling and organisation of the earthquakes or of the dikes, distribution of eruptive vents and orientation of fissures, and investigate how all these interactions contribute to the evolution of volcanism and architecture of magma storage.
