Editorial: Field Data, Models and Uncertainty in Hazard Assessment of Pyroclastic Density Currents and Lahars: Global Perspectives

Abstract

Pyroclastic density currents (PDCs) and lahars are two of the most destructive phenomena that are generated at volcanoes worldwide. Therefore, assessing their volcanic hazard is a primary step towards the estimation (and reduction) of volcanic risk around volcanoes. In this Editorial, we present a compilation of Original Research manuscripts that study PDCs and lahars, and contribute to different components of their volcanic hazard assessment. Taking these global perspectives into account, we also provide our own expert judgment on what future directions might be taken to keep improving these PDC and lahar hazard assessments moving forward.
