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.

Frontiers in Earth Science, 2017 This study presents a new method for producing long-term hazard maps for pyroclastic density currents (PDC) originating at Campi Flegrei caldera. Such method is based on a doubly stochastic approach and is able to combine the uncertainty assessments on ...

Vegetation dieback as a proxy for temperature within a wet pyroclastic density current: A novel experiment and observations from the 6th of August 2012 Tongariro eruption [PDF]
, 2014 The 6th of August 2012 eruption of Te Maari (Mt Tongariro, New Zealand) generated wet pyroclastic density currents (PDCs) which caused widespread dieback of vegetation (singed, brown foliage) in their path.

Turbulent particle-gas feedback exacerbates the hazard impacts of pyroclastic density currents
Communications Earth & EnvironmentCausing one-third of all volcanic fatalities, pyroclastic density currents create destruction far beyond our current scientific explanation. Opportunities to interrogate the mechanisms behind this hazard have long been desired, but pyroclastic density ...

Syn-eruptive, soft-sediment deformation of deposits from dilute pyroclastic density current: triggers from granular shear, dynamic pore pressure, ballistic impacts and shock waves [PDF]
Solid Earth, 2015 Soft-sediment deformation structures can provide valuable information about the conditions of parent flows, the sediment state and the surrounding environment. Here, examples of soft-sediment deformation in deposits of dilute pyroclastic density currents

The fragmentation-induced fluidisation of pyroclastic density currents [PDF]
Nature Communications, 2023 AbstractPyroclastic density currents (PDCs) are the most lethal volcanic process on Earth. Forecasting their inundation area is essential to mitigate their risk, but existing models are limited by our poor understanding of their dynamics. Here, we explore the role of evolving grain-size distribution in controlling the runout of the most common PDCs ...

Tracking a Pyroclastic Density Current With Seismic Signals at Mt. Etna (Italy)
Journal of Geophysical Research: Solid Earth, 2023 Pyroclastic density currents (PDCs) are dangerous flows of volcanic rock and gas that are the most deadly proximal volcano hazard. There is significant interest in better understanding PDC dynamics, however, they are challenging to study due to their ...

Radar Backscatter and Emissivity Models of Proposed Pyroclastic Density Current Deposits on Venus
Journal of Geophysical Research: Planets, 2022 Magellan synthetic aperture radar observations of Venus revealed a small number of deposits in the highland regions that were suggested to have formed from pyroclastic density currents.
