Mineral-Melt Equilibria and Geothermobarometry of Campi Flegrei Magmas: Inferences for Magma Storage Conditions [PDF]
Minerals (Basel, Switzerland), 2022 The eruptions of Campi Flegrei (Southern Italy), one of the most studied and dangerous active volcanic areas of the world, are fed by mildly potassic alkaline magmas, from shoshonite to trachyte and phonotrachyte. Petrological investigations carried out in past decades on Campi Flegrei rocks provide crucial information for understanding differentiation

We present Magma, a write-optimized high data density key-value storage engine used in the Couchbase NoSQL distributed document database. Today's write-heavy data-intensive applications like ad-serving, internet-of-things, messaging, and online gaming, generate massive amounts of data.

Magma accumulation at depths of prior rhyolite storage beneath Yellowstone Caldera
Science, 2022Seismic tomography has provided key insight into Yellowstone’s crustal magmatic system that includes attempts to understand the melt distribution in the subsurface and the current stage of the volcano’s life cycle. We present new tomographic images of the shear wave speed of the Yellowstone magmatic system based on full waveform inversion of ambient ...

The storage and release of magma on Mount Etna
Journal of Volcanology and Geothermal Research, 1977Abstract The eruptive history of Etna during the past 450 years provides data on effusion rates, volumes of magma involved, and the nature of the eruptive conduits. These data are interpreted in terms of a two-part intravolcanic magma reservoir which feeds the flank eruptions through dike-like conduits.

Magma storage prior to the 1912 eruption at Novarupta, Alaska
Contributions to Mineralogy and Petrology, 2002New analytical and experimental data constrain the storage and equilibration conditions of the magmas erupted in 1912 from Novarupta in the 20th century's largest volcanic event. Phase relations at H2O+CO2 fluid saturation were determined for an andesite (58.7 wt% SiO2) and a dacite (67.7 wt%) from the compositional extremes of intermediate magmas ...

The storage and release of magma on mount Etna: a discussion
Journal of Volcanology and Geothermal Research, 1979In a recent paper, Wadge (1977 [1] *) at tempts to demonstrate quantitatively that magma stored in the main central conduit of Etna is capable of hydraulically fracturing the surrounding rocks and propagating a dike-like eruptive fissure a mechanism that had been previously advocated to account for the flank eruptions o f the Sicilian volcano (e.g. Rit

Dynamics of magma storage in the summit reservoir of Kilauea Volcano, Hawaii
Journal of Geophysical Research: Solid Earth, 1992An eruption of Kilauea Volcano, Hawaii, normally results in a decrease in the internal pressure of a summit magma reservoir as it partly drains. The interior of the volcano responses to the decrease in pressure (1) by elastic expansion of remaining magma and gas, (2) additional exsolution of gas dissolved in the magma, and (3) by contraction of the ...
