Information - GMPV17 Physics and chemistry of magmatic degassing
Event Information
Magmatic degassing strongly controls both the style and power of
volcanic eruptions. Degassing occurs during magma ascent and
depressurization from depth to the surface and has a profound control on
whether the eruption of magma is explosive or effusive. During quiescent
periods volcanoes can release large amounts of volatiles, whilst
appearing geophysically inactive. Thus, monitoring of the degassing
process constitutes a powerful tool for the surveillance of volcanoes.
Voluminous degassing observed during both eruptive and quiescent periods
also has a profound effect on the Earth's atmosphere and environment on
all time scales. From being the source of most gases in the atmosphere
over geologic time scales, to producing climate change, to threatening
aviation, magmatic gas sources provide a strong link between the
lithosphere and society. We invite contributions which highlight
progress and innovation in our understanding of magmatic gas release.
