Title:

“The dynamics of pyroclastic density currents in super-volcano eruptions”

Pyroclastic Density Currents (PDC) are one of the deadliest and most dangerous volcanic hazard. However, these flows possess a high mobility leading to unexpected long runouts which mechanisms are still poorly understood. In the case of super-eruptions, these violent flows can travel tens of kilometres from their source and climb high topographic barriers. Using the exceptionally preserved 232 AD Taupo Ignimbrite, I will use a combination of field mapping and large-scale experiments in the eruption simulator PELE to reproduce these hot flows with natural material. This work seeks to bring new elements in the understanding of large-scale PDCs and to answer one or several of the following questions. What are the fundamental transport and deposition mechanisms of PDCs produced in high-magnitude super-volcano eruptions, and how do they differ from those of smaller-volume? What is the influence of heat on the behaviour of PDCs? How can we model hazard impact of such extreme geohazards, including their ability to surmount terrains, and thus forecast impacts of future eruptions?
