These studies report observations at all volcanoes, including those at which no deformation is observed and are compiled to form the catalogue of 540 systematically studied volcanoes used for the statistical analysis of the link between deformation and eruption. Each volcano is assigned two distinct states: either ‘deformed’ or ‘not deformed’ and either ‘erupted’ or ‘not erupted’ which apply to the entire time period regardless of the temporal relationship of deformation and eruption. Further details are given in Supplementary Table 1.
