Volcanic conduits, through which magma travels from its crustal storage region to the surface, play a fundamental role in shaping the nature of eruptions and associated phenomena. It has been well established that magma may flow, stall, crystallise, degas, and fragment in the conduit, that fluids migrate in and out of the conduit, and that seismic and acoustic waves are generated and travel within the conduit. Understanding the processes that occur in volcanic conduits is of paramount importance for improving prediction of eruption style, evolution, and duration. However, despite escalating advances in the characterisation of individual conduit processes, our understanding of their mutual interactions and the consequent control on volcanic activity is still limited. This session will address this topic head-on. We particularly encourage contributions that address this topic through integration of at least two of experimental, numerical, observational, and analytical/petrological approaches.
