This dataset contains the spatial distribution of mean damage in RV1 at the building level produced by a Pyroclastic Density Current hazard scenario, as presented in the associated study.

The mean damage is evaluated at the building level within a virtual testbed representative of typical Italian coastal urban contexts, Coastal Returnville (RV1). For visualization consistent with the figures presented in the paper, the provided .lyrx files should be applied to the shapefile. Coordinate system WGS84 – 33N
