Submission deadline is February 18, 2019. â??Volatile constraints on magma plumbing systems and eruption dynamics at open-conduit volcanoesâ?? Among the 1551 volcanoes recognized to be active on Earth, only about a hundred displays continuous eruptive activity or/and persistent degassing with sizeable plume emissions, implying that their conduit remains open. Illustrative examples include Nyiragongo, Kilauea, Etna, Stromboli, Colima, Masaya, Villarica, Merapi, Asama, Sakurajima, Ambrym, Yasur, etc. These continuously active volcanoes erupt various magma types, in different tectonic settings, and their eruptive styles cover a wide range from purely effusive (e.g. lava lakes) to violently explosive. They thus offer remarkable opportunities for real-time investigations of magmatic and volcanic processes, for deciphering the dynamics of magma plumbing systems, and for the testing of new technologies and new models. Moreover, many of these volcanoes are located in densely inhabited regions of the world, which fully justifies that they be closely surveyed. Given the key role of magmatic volatiles in the dynamics of magma ascent and volcanic eruptions, studying the composition and flux of gas emissions from these volcanoes, as well as the pressure-related behavior of volatiles dissolved in their magmas, is one important approach to broadly understand how volcanoes work. Such studies have been widely developed in recent decades on the above volcanoes, allowing great achievements. In this symposium, we invite research contributions dealing with both field measurements, laboratory analyses, and theoretical modelling of magma degassing and volcanic gas release in relation to eruptive phenomena at open-conduit volcanoes. Cutting-edge studies involving ground-based and space-borne remote sensing tools, new unmaned platforms, and high-resolution geochemical/petrological tracers are particularly welcomed. The Symposium will be organized in order to give maximum allowance to both case studies and review talks, as well as discussions.
