"Hot and sticky" and "cold and damp" pyroclastic eruptions, and their relationship with topography: valley- and lake-filling ignimbrites, Ardnamurchan, NW Scotland

Volcanica
Pyroclastic density currents are complex mixtures of rock, ash and gas and represent significant hazards at many active volcanoes worldwide. Ignimbrites are the deposits of pyroclastic density currents and can be used to record the eruption dynamics and ...

The footprint of column collapse regimes on pyroclastic flow temperatures and plume heights

Nature Communications, 2019
Pyroclastic density currents (PDCs) are a major threat during explosive volcanic eruptions, hence the possibility to forecast them would be a vital improvement for risk mitigation. Here the authors present a 3D flow model to quantify the thermal patterns

The impact of volcanic eruption rate on pyroclastic hazard

Communications Earth & Environment
Pyroclastic density currents – fast flows of hot gases, ash, and debris – are some of the most hazardous phenomena associated with explosive volcanic eruptions.

Rock characteristics of post-caldera volcanoes in Dieng volcanic complex (DVC), Central Java, Indonesia

JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2022
The Dieng volcanic complex (DVC) has one of the densest post-caldera volcanisms activity presents in Indonesia, yet its population density is considerably high.

Isolation, Insularity and Resilience: A Review of the Geophysical, Socioeconomic, and Environmental Vulnerabilities of Gran Canaria and Lesvos Islands for Policy Interventions to Global Change

Sustainable Development, EarlyView.
ABSTRACT The dynamic nature of small islands being geographically isolated and their perceived connectedness with global networks complicates research attempts to draw general conclusions on whether insularity leads to marginalization or strengthens their resilience for sustainable development.

The fluidization behaviour of ignimbrite at high temperature and with mechanical agitation [PDF]

, 2004
Experiments were carried out to study the fluidization behaviour of ignimbrite at high temperature and while being mechanically agitated. Geldart group C behaviour occurs up to 565 degreesC when the material is subjected to increasing gas flow ( without ...

Investigating Technology and Raw Materials Source of the Archaic and Classical Architectural Terracottas From the Athenaion in Castro (Apulia, Italy)

Archaeometry, EarlyView.
ABSTRACT Since 2000, archaeological excavations have brought to light the sanctuary of Athena in Castro (Apulia, Italy), including terracotta roofs dated between the 6th and 4th centuries bce. Based on their morphological and stylistic features, it is suggested that the terracotta items were manufactured in the Greek colony of Taras (modern Taranto ...

Dynamics of pyroclastic density currents : : a thesis presented in partial fulfilment of the requirements for the degree of Doctor of Philosophy in Earth Sciences at Massey University, Palmerston North, New Zealand [PDF]

, 2016
Listed in 2016 Dean's List of Exceptional ThesesPyroclastic density currents (PDCs) are the most dangerous mass flows on Earth. Yet they remain poorly understood because internal measurements and observations are hitherto non-existent.

A hypothesis of sudden body fluid vaporization in the 79 AD victims of Vesuvius. [PDF]

, 2018
In AD 79 the town of Herculaneum was suddenly hit and overwhelmed by volcanic ash-avalanches that killed all its remaining residents, as also occurred in Pompeii and other settlements as far as 20 kilometers from Vesuvius.
