Anticipating volcanic eruptions:
developing multidisciplinary tools to track the source, volume and
duration of magma movement from the mantle to the surface

Magma input in the deep supply system is the early signal of a possible reactivation of the whole plumbing system. Thus to understand how magma is transferred from depth it is pivotal to recognise long to midterm precursors of volcanic unrest. The workshop aims to develop synergies between complementary expertise, toward the unique objective to quantify the origins, volumes and durations of magma movement from mantle to the surface. This has important implications on the monitoring strategies, risk mitigation and will also provide hints for a generalized models on how volcanoes work.
These specific issues will be addressed:

• definition of mechanisms, time scales and periodicities of deep magma supply;
• definition of rates and magma volume transfer between different regions of the volcanic system;
• characterization of mechanisms of interactions between magmas/host rock within the intermediate storage system and during the ascent to the eruptive system;
• interaction of the ascending mafic magma with crustal bodies of more evolved magma and crystal mush;
• definition of relationship between the above processes and the eruptive style, magnitude and intensity of eruptions, eruptive scenarios and associated hazard;
• recognition of possible precursors and improvement of monitoring actions.
