• Volcanology and igneous processes: field, petrology, geochemistry, and texture • Processes and timescales of magma solidification • Link between intracrystalline deformation and regional tectonics • Deformation of olivine crystals in the magma plumbing system of shield and arc volcanoes • Status of volcanic activity, degassing and eruption processes of subduction volcanoes • Gas-ash interaction in the volcanic plume, inferred from volatile chemistry of ash leachates and ash texture
