Journal Article
Walding, N., Williams, R., Rowley, P., Dowey, N., Parsons, D., & Bird, A. (2025). Behaviours of pyroclastic and analogue materials, in dry and wet environments, for use in experimental modelling of pyroclastic density currents. Volcanica, 8(1), 261-285. https://doi.org/10.30909/vol/oxkm9163

Modelling pyroclastic density currents (PDCs) is a challenging yet essential element of hazard assessment. PDCs are unpredictable and internal processes are often difficult to measure directly. Analogue experiments have been an important tool for inv...
