It is well known that explosive volcanic eruptions pose serious hazards to local communities and may have worldwide impacts. However, the products of explosive eruptions on volcanic ocean islands are almost inevitably incompletely preserved as a ...

Role of volatiles in highly explosive basaltic eruptions
The increase in mass eruption rate due to the presence of volatiles in explosive basaltic eruptions is greatly dependent on the type of volatile, according to numerical modelling. CO2 has a very limited effect unless injected from an external source.

A model for large-scale volcanic plumes on Io: Implications for eruption rates and interactions between magmas and near-surface volatiles. [PDF]
Volcanic plumes deposit magmatic pyroclasts and SO2 frost on the surface of Io. We model the plume activity detected by Galileo at the Pillan and Pele sites from 1996 to 1997 assuming that magmatic eruptions incorporate liquid SO2 from near-surface ...

Magmatic volatiles in explosive rhyolitic eruptions
Obsidian clasts in rhyolitic tephra deposits preserve preemption magmatic volatile contents, providing a direct means for determining the volatile content of explosively erupted magmas. Small to moderate volume Plinian eruptions (10−3 to 10−1 km³) appear to be driven by 0.5‐1.0 wt.% volatiles, consisting dominantly of H2O with minor CO2.

Abstract Drawing on Laclau and Mouffe's poststructuralist discourse theory, this article critically examines the von der Leyen Commission's agricultural trade policy under the European Green Deal. It elucidates the shift from a dominant neoliberal trade logic to open strategic autonomy, positioning agricultural trade as a foreign policy instrument. The

Periodontitis and Periodontal Conditions in Systemically Healthy Children and Adolescents
ABSTRACT Objective To answer the PICoS question ‘in systemically healthy children and adolescents (Population), what are the main features of periodontitis, necrotising periodontal diseases (NPD) and other periodontal conditions (periodontal abscesses, endo‐periodontal lesions, traumatic occlusal forces, prosthesis‐ and tooth‐related factors ...

Shallow magma diversions during explosive diatreme-forming eruptions
Shallow magmatic feeder systems in monogenetic volcanic fields may determine how a volcano erupts. Here, the authors use numerical modeling to show that explosive excavation and infilling of eruptive craters affects local stress states, with feedbacks ...

Vectors and Vector‐Borne Diseases: Biology, Epidemiology and Integrated Control Strategies
ABSTRACT Vector‐Borne Diseases (VBDs), transmitted by arthropods such as mosquitoes, ticks, fleas and sandflies, represent a significant threat to global health. These diseases can be caused by a variety of pathogens, including bacteria, viruses, protozoa, and helminths.

The dynamics of Earth’s largest, most voluminous eruptions (≥ 100 km3 ejecta; VEI 7) are poorly understood. Here, we explore the question of whether these very large eruptions can be treated as scaled-up versions of moderate volume historical eruptions ...
