Volcanoes are among the most important natural hazards able to produce serious consequences to human habitats and large-scale economies. A global understanding of how magmatic processes work prior to eruption plays a fundamental role in the assessment of volcanic hazard and the mitigation of potential risk. During the last two decades, the advancement in volcanic monitoring networks,together with the development of more precise and accessible analytical techniques, have led to better constraints on the physical and chemical processes affecting magmas en route to the surface (i.e., storage/crystallization conditions, contamination, mixing, degassing). Great advances in the calculation of timescales of pre- and syn-eruptive processes have brought new insight into the mechanisms and durations of magma residence and ascent throughout the lithosphere. Nonetheless, a great point of discussion is still related to how this knowledge can contribute to the definition of plans of mitigation of volcanic risk,also in terms of highlighting of eruptive precursors.We invite submissions related to field and experimental volcanology, petrology,and geochemistry, that contribute to improve our current knowledge on magma dynamics and pre-eruptive timescales, and explore how these results can be linked with other disciplines and/or technologies, in terms of mitigation of volcanic risk.
