Volcanoes emit larger amounts of volcanic gas than can be dissolved in the volume of erupted magma during a variety of volcanic processes, including explosive and effusive eruption and noneruptive continuous degassing. Degassing of unerupted magma with a much larger volume than that of erupted magma caused such a large degassing; erupted magma represents only a small portion of the magma that drives volcanic activity. Evaluation of the magma‐gas differentiation process causing the excess… 

Degassing during quiescence as a trigger of magma ascent and volcanic eruptions

It is demonstrated that magma ascent can be triggered by the passive release of gas during quiescence, which induces the opening of pathways connecting deep and shallow magma reservoirs, which contrasts with the more common bottom-up mechanisms in whichMagma ascent is only driven by processes occurring at depth.

On depressurization of volcanic magma reservoirs by passive degassing

Many active volcanoes around the world alternate episodes of unrest and mildly explosive eruptions with quiescent periods dominated by abundant but passive gas emissions. These are the so‐called

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) volcanoes—produce high gas fluxes

Bubble accumulation and its role in the evolution of magma reservoirs in the upper crust

This work investigates the fluid dynamics that controls the transport of the MVP in crystal-rich and crystal-poor magmas, and shows how the interplay between capillary stresses and the viscosity contrast between the MVP and the host melt results in a counterintuitive dynamics, whereby the MVP tends to migrate efficiently incry-rich parts of a magma reservoir and accumulate in crystals-poor regions.

The Role of Volatiles in the Genesis, Evolution and Eruption of ARC Magmas

The subduction zone volatile cycle is key to understanding the petrogenesis, transport, storage and eruption of arc magmas. Volatiles control the flux of slab components into the mantle wedge, are

Persistent gas emission originating from a deep basaltic magma reservoir of an active volcano: the case of Aso volcano, Japan

Volcanic gas emission is considered to reflect the degassing of magma beneath volcanoes. The combined observations of gas measurement and petrological study are expected to constrain the volatile

Pre-eruptive excess volatiles and their relationship to effusive and explosive eruption styles in semi-plugged volcanoes

Understanding the role of various factors influencing eruption style is challenging, but it can aid in adapting different hazard mitigations and crisis responses for explosive or effusive events.



Petrological and volcanological constraints on volcanic sulfur emissions to the atmosphere

A review of current knowledge about the physics of volcanic eruptions and the experimental constraints on sulfur behavior in magmas is presented with the aim of evaluating the range of sulfur yields

Endogenous growth of persistently active volcanoes

LAVA lakes and active strombolian vents have persisted at some volcanoes for periods exceeding the historic record. They liberate prodigious amounts of volatiles and thermal energy but erupt little

On the role of hydrothermal systems in the transfer of volcanic sulfur to the atmosphere

The behaviour of magmatic volatiles dictates various aspects of a subaerial volcano's eruptive style, morphology, and potential impact on the atmosphere. Typically, when volatiles bleed from

The relationship between fumarole gas composition and eruptive activity at Galeras Volcano, Colombia

Forecasting volcanic eruptions is critical to the mitigation of hazards for the millions of people living dangerously close to active volcanoes. Volcanic gases collected over five years from Galeras

Sulphur output and magma degassing budget of Stromboli volcano

STROMBOLI volcano in the Aeolian islands has been erupting continuously for more than 2,000 years1, and probably as many as 5,000, following a major flank collapse2,3. Here we describe air-borne

A basalt trigger for the 1991 eruptions of Pinatubo volcano?

THE eruptive products of calc-alkaline volcanos often show evidence for the mixing of basaltic and acid magmas before eruption (see, for example, refs 1, 2). These observations have led to the

Excessive degassing of Izu-Oshima volcano: magma convection in a conduit

Excess degassing of magmatic H2O and SO2 was observed at Izu-Oshima volcano during its latest degassing activity from January 1988 to March 1990. The minimum production rate for degassed magma was

Explosive basaltic volcanism from Cerro Negro volcano: Influence of volatiles on eruptive style

The 1992 and 1995 basaltic eruptions of Cerro Negro volcano, Nicaragua, had contrasting eruptive styles. Although they were nearly identical in composition, the 1992 eruption was explosive, producing
