A database of pyroclastic density current deposit characteristics compiled from a literature review (PDCD-Dat v.2026)
A database of pyroclastic density current deposit characteristics. The database includes both quantitative datasets (e.g., grain size, density, bedform dimensions, thickness) and qualitative descriptors (e.g., sedimentary structures, lithofacies). PDCD-DAT includes data from 85 source publications, covering 97 eruptions or eruptive phases, and 214 individual depositional units from 55 globally distributed volcanoes. Eruptions recorded in the database range from VEI 1-8. A website is currently being built which will host the searchable database,

- Statement
- Data were mostly obtained from published studies but also, from unpublished studies by the authors. The database focussed on collating high-quality quantitative datasets and example datasets for the least frequently reported properties. We used the FlowDat database (Ogburn, 2012; 2025) as a starting point to identify target PDC deposits and sources of PDC deposit data. We focused on eruptions in FlowDat for which quantitative data were already recorded for one or more of the following bulk PDC properties or mobility metrics: total flow bulk volume, total flow planimetric area, runout, and H/L. This approach was chosen to enable users of the database to explore the relationships between PDC deposit properties and other PDC properties/mobility metrics. We searched the literature for studies on PDC deposits associated with these eruptions and relevant peer-reviewed studies containing at least one form of quantitative data were incorporated into the database. The full methodology is described in the manuscript PDCD-DAT – A global database of pyroclastic density current deposit field data published in the Journal of Applied Volcanology.
