This slides have been presented to the W06 workshop on "Benchmarking volcano models" at IAVCEI 2013 (Kagoshima, Japan).
The presentation introduces a hierarchy of fluid dynamics models for pyroclastic density currents (PDC) and the problem of estimating their related uncertainties.
A validation metrics based on hazardous actions and a "validation hierarchy" are discussed. Finally, a benchmark for PDC models is proposed.
