Environmental impact of volcanic emissions
Co-organized as AS3.30, co-sponsored by EAG
Convener: Marcello Liotta | Co-conveners: Julia Arndt, Sergio Calabrese, Evgenia Ilyinskaya

Volcanoes emit large amounts of gaseous species and particulates into the atmosphere as well as onto the Earth’s surface. Based on their geochemical behavior, the volcanogenic elements move in several ways. The most refractory ones travel by solid particles and lava flows, semi-volatiles are usually abundant in volcanics but significant amounts are also emitted as gaseous chlorides and aerosol, and volatiles are mainly emitted as gaseous phases. Therefore, violent eruptions and effusive activity, but also quiescent degassing represent important sources of volcanogenic elements that affect the surroundings of the volcanic environments. The understanding of the processing governing the mobility and the dispersion of volcanic elements is fundamental for constraining the environmental impact of volcanic emissions.
We are seeking contributions from various fields on topics including (but not limited to):
- challenges for emission monitoring on different volcanoes all over the world
- emission monitoring techniques and optimization/validation of these
- biomonitoring techniques to investigate the areal dispersion of volcanic emissions
- emission of main gases and trace elements from volcanoes
- effects of volcanic emissions on the immediate surrounding environment, on the vegetation and on human health
- emissions from eruptive and quiescent degassing of volcanoes
- speciation analyses of emitted elements
- atmospheric chemistry in the unique gas composition of volcanic plumes
- role of atmospheric deposition in the cycle of volcanogenic elements
