A plethora of different processes occur within volcanic plumbing systems, such as magma crystallization, vesiculation, assimilation, mixing, fluid transfer, chamber replenishment, mush rejuvenation, cooling and decompression. All of these processes influence the triggering mechanisms of eruptions, the magma rheology, ascent dynamics within the conduit, fragmentation mechanisms, and therefore, the eruptive style of volcanoes.

Unraveling and constraining the pre- and syn-eruptive conditions of volcanic systems is of paramount importance for volcanologists, petrologists, geochemists and geophysicists to provide better short-term forecasts of eruption onset and the time-scales of volcanic processes. Improved knowledge of magma dynamics within the crust or at the surface is fundamental for volcanic hazard assessment and mitigation

Volcanic eruptions are usually preceded by long or short periods of volcanic unrest. However, the time-scales of volcanic unrest are not well constrained. Magma production and migration, its geochemical evolution, the residence time within the crust, the eruption triggers and the style of the eruption, all remain fundamental questions. Furthermore, the connection between surface observations and deep magmatic processes still remain uncertain. The goal of this Research Topic is to provide a deeper understanding of magma storage and transport, the processes leading to the onset of eruptions, and the emplacement mechanisms of the related volcanic phenomena. Combined field observations, experimental and laboratory analyses, numerical modeling and geophysical studies help us to constrain pre- and syn-eruptive conditions and define the links between magma reservoir evolution, eruption triggers and the time scale of eruptive events.

The scope of this Research Topic is to stimulate studies with multidisciplinary approaches that explore pre-eruptive conditions, magma dynamics during ascent and time-scales of processes active in volcanic plumbing systems. The combination of petrological and volcanological data with geophysical observations such as seismic activity and ground deformation is fundamental for further understanding of processes and conditions that lead volcanic unrest, eruption triggers and magma dynamics in volcanic plumbing systems.

We welcome contributions that discuss the recent advances in our understanding of pre- and syn-eruptive conditions of effusive and explosive eruptions in different tectonic settings. Therefore, contributions based on field, petrological, geochemical, seismic and modeling approaches, aiming to unravel plumbing system dynamics and time-scales of eruptive events are welcome to this Research Topic.
