Effect of the dataset dimension on the extension of the hazard maps. The plot represents the extension of the area enclosed in the 5 % probability contour for a tephra loading of 300 kg/m2 for different population of the wind dataset, from 1 – 20 years. The ECMWF ERA Interim (ERAI) dataset was used. The first year of each dataset was kept fixed at 1991
