Quantifying deformation and fluid dynamics in a developing model volcanic plumbing system
Janine Kavanagh, lecturer at University of Liverpool, will present her work on "Quantifying deformation and fluid dynamics in a developing model volcanic plumbing system"

The mechanics of magma transport are important for understanding magma distribution within the shallow crust and the tendency for intrusion or eruption. I will present the results from a series of layered gelatine analogue experiments analysed by Particle Image Velocimetry (PIV) and Digital Image Correlation (DIC) to document the fluid flow and small-scale deformation processes that occur during dyke and sill emplacement. The analysis provides new insights into the dynamics of sill formation by allowing small-scale stress and strain perturbations within the host to be measured at the time of sill inception. This work has important implications for interpreting surface and sub-surface signals associated with magma flow beneath active volcanoes.
