The build-up and triggers of volcanic eruptions
More than 800 million people live in proximity to active volcanoes and could be directly
impacted by potential eruptions. Mitigation of future volcanic hazards requires adequate …

Deep carbon emissions from volcanoes
MR Burton, GM Sawyer… - Reviews in Mineralogy …, 2013 - pubs.geoscienceworld.org
Over long periods of time (~ Ma), we may consider the oceans, atmosphere and biosphere
as a single exospheric reservoir for CO2. The geological carbon cycle describes the inputs …

Carbon dioxide emissions from subaerial volcanic regions
Volcanism and metamorphism are the principal geologic processes that drive carbon
transfer from the interior of Earth to the surface reservoir. 1–4 Input of carbon to the surface …

Open-vent volcanoes fuelled by depth-integrated magma degassing
Open-vent, persistently degassing volcanoes—such as Stromboli and Etna (Italy), Villarrica
(Chile), Bagana and Manam (Papua New Guinea), Fuego and Pacaya (Guatemala) …

Along-arc, inter-arc and arc-to-arc variations in volcanic gas CO2/ST ratios reveal dual source of carbon in arc volcanism
Some 300–600 Tg of volatiles are globally vented each year by arc volcanism. Such arc gas
emissions have contributed to past and present-day evolution of the Earth atmosphere and …

Sulfur degassing from volcanoes: source conditions, surveillance, plume chemistry and earth system impacts
C Oppenheimer, B Scaillet… - Reviews in mineralogy …, 2011 - pubs.geoscienceworld.org
Despite its relatively minor abundance in magmas (compared with H2O and CO2), sulfur
degassing from volcanoes is of tremendous significance. It can exert substantial influence …

Volcanic CO2 tracks the incubation period of basaltic paroxysms
The ordinarily benign activity of basaltic volcanoes is periodically interrupted by violent
paroxysmal explosions ranging in size from Hawaiian to Plinian in the most extreme …

Strong constraint on modelled global carbon uptake using solar-induced chlorophyll fluorescence data
Accurate terrestrial biosphere model (TBM) simulations of gross carbon uptake (gross
primary productivity–GPP) are essential for reliable future terrestrial carbon sink projections …

Mafic magma feeds degassing unrest at Vulcano Island, Italy
The benign fuming activity of dormant volcanoes is punctuated by phases of escalating
degassing activity that, on some occasions, ultimately prelude to eruption. However …

Vapor-bubble growth in olivine-hosted melt inclusions
Melt inclusions record the depth of magmatic processes, magma degassing paths, and
volatile budgets of magmas. Extracting this information is a major challenge. It requires …
