Rapid pre-eruptive thermal rejuvenation in a large silicic magma body: the case of the Masonic Park Tuff, Southern Rocky Mountain volcanic field, CO, USA

Determining the mechanisms involved in generating large-volume eruptions (>100 km³) of silicic magma with crystallinities approaching rheological lock-up (~50 vol% crystals) remains a challenge for volcanologists...

The use of biotite trace element compositions for fingerprinting magma batches at Las Cañadas volcano, Tenerife

Accurate identification of individual volcanic events in the field is crucial for constraining eruption volumes and calculating recurrence intervals between eruptive episodes. Due to complexities of pyroclasti...

Geochronological and isotopic records of crustal storage and assimilation in the Wolverine Creek–Conant Creek system, Heise eruptive centre, Snake River Plain

Understanding the processes of differentiation of the Yellowstone–Snake River Plain (YSRP) rhyolites is typically impeded by the apparent lack of erupted intermediate compositions as well as the complex nature...

MeMoVolc report on classification and dynamics of volcanic explosive eruptions

Classifications of volcanic eruptions were first introduced in the early twentieth century mostly based on qualitative observations of eruptive activity, and over time, they have gradually been developed to in...

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

Here, the authors model the fluid dynamics that controls the transport of the magmatic volatile phase (MVP) in crystal-rich and crystal-poor magmas; they find that the MVP tends to migrate efficiently in cryst...

Groundmass crystallisation and cooling rates of lava-like ignimbrites: the Grey’s Landing ignimbrite, southern Idaho, USA

Constraining magmatic and eruptive processes is key to understanding how volcanoes operate. However, reconstructing eruptive and pre-eruptive processes requires the ability to see through any post-eruptive mod...

Characterization of tephra deposits with limited exposure: the example of the two largest explosive eruptions at Nisyros volcano (Greece)

Explosive eruptions associated with tephra deposits that are only exposed in proximal areas are difficult to characterize. In fact, the determination of physical parameters such as column height, mass eruption...

SPICE Level 3 - Experience with Using E-Learning to Coach the Use of Standard System Design Best Practices in Projects

Most improvement initiatives focus on assessments and derived improvement plans. However, the effort to really implement and sustain improvements is much bigger than the assessment effort. Also, it is crucial ...

Controls on magma permeability in the volcanic conduit during the climactic phase of the Kos Plateau Tuff eruption (Aegean Arc)

X-ray computed microtomography (µCT) was applied to pumices from the largest Quaternary explosive eruption of the active South Aegean Arc (the Kos Plateau Tuff; KPT) in order to better understand magma permeab...

Application of the multi distribution function lattice Boltzmann approach to thermal flows

Numerical methods able to model high Rayleigh (Ra) and high Prandtl (Pr) number thermal convection are important to study large-scale geophysical phenomena occuring in very viscous fluids such as magma chamber dy...

Insights into shallow magmatic processes in large silicic magma bodies: the trace element record in the Fish Canyon magma body, Colorado

Highly evolved rhyolite glass plus near-solidus mineral assemblages in voluminous, dacitic, crystal-rich ignimbrites provide an opportunity to evaluate the late magmatic evolution of granodiorite batholiths. T...

Cardiopulmonary and metabolic responses in healthy elderly humans during a 1-week hiking programme at high altitude

Worldwide there are approximately 100 million visitors to high altitude annually and about 15% of those are elderly. Nevertheless, basic information on the cardiopulmonary and metabolic responses to physical ...
