Article
Full-text available
The deployment of small uncrewed aerial vehicles (sUAVs) for volcanological applications has grown over the last decade, mainly attributed to the development of affordable, smaller, and versatile platforms. However, the use of sUAVs in active volcanic regions is a challenging operation conducted under extreme environmental conditions. The here repo...

Pyroclastic surges are lethal hazards from volcanoes that exhibit enormous destructiveness through dynamic pressures of 10 ⁰ –10 ² kPa inside flows capable of obliterating reinforced buildings. However, to date, there are no measurements inside these currents to quantify the dynamics of this important hazard process. Here we show, through large-sca...
Data
This repository contains data presented in the article “Destructiveness of pyroclastic surges controlled by turbulent fluctuations” by E. Brosch, G. Lube, M. Cerminara, T. Esposti-Ongaro, E.C.P. Breard, J. Dufek, B. Sovilla and L. Fullard. The article was published in Nature Communications (https://doi.org/10.1038/s41467-021-27517-9). A readme fil...

Numerical results of a two-layer depth-averaged model of pyroclastic density currents (PDCs) were compared with an experimental PDC generated at the international eruption simulator facility (the Pyroclastic flow Eruption Large-scale Experiment (PELE)) to establish a minimal dynamical model of PDCs with stratification of particle concentrations. In...

Full-text available
The aim of this document is to define a Pyroclastic Density Currents (PDCs) benchmark based on a large-scale experiment to be used with numerical models at different levels of complexity. The document is organized as follows. Section 2 concisely describes the large-scale laboratory experiment setup and geometry, and the relevant specific bibliograp...

Full-text available
Dilute pyroclastic density currents (dilute PDCs) are frequent and highly dangerous flows of hot gas and particles occurring at explosive volcanoes. The study and interpretation of the sedimentary characteristics of their associated deposits is one of the most important approaches to better understand these violent phenomena and to characterise the...
