Abrasion in pyroclastic flows [PDF]
Geologische Rundschau, 1992 The relative size of glass rims coating crystals in the matrix ash provides a semi-quantitative measure of abrasion of ash grains in pyroclastic flows. Median abrasion indices (= areacrystal / areaglass rim) are 8.4 to 18.5 in Laacher See pyroclastic flow units but only 4 to 6.3 in assocciated fallout, showing stronger abrasion of ash particles in the ...

Permian Large Igneous Provinces and Their Paleoenvironmental Effects
Geophysical Monograph Series, Page 417-434., 2021 Exploring the links between Large Igneous Provinces and dramatic environmental impact
An emerging consensus suggests that Large Igneous Provinces (LIPs) and Silicic LIPs (SLIPs) are a significant driver of dramatic global environmental and biological changes, including mass extinctions.

The impact of pyroclastic density currents duration on humans: the case of the AD 79 eruption of Vesuvius [PDF]
Scientific Reports, 2021 Pyroclastic density currents are ground hugging gas-particle flows that originate from the collapse of an eruption column or lava dome. They move away from the volcano at high speed, causing devastation.

Fluidization in pyroclastic flows
Powder TechnologyPyroclastic flows are mixtures of gas and particles generated by gravitational collapse of lava domes or fall-back of eruption columns during explosive eruptions. They are major natural hazards because they can propagate far away from the source at speeds that largely exceed those of most natural or anthropogenic granular flows.

Evolution Magmatism of Nagasari Volcano Dieng, Central Java, Indonesia
JGEET: Journal of Geoscience, Engineering, Environment and Technology, 2022 Nagasari Volcano, part of the Dieng volcanic complex, is one of the unique volcanoes in Central Java. Around this volcano grow eruption craters, volcanic cones, and pyroclastic flow ridges. There were several 14 eruption centers around Mount Nagasari, so
