Fig. 6

a. Distances between the centre of deformation and the nearest edifice catalogued in the VOTW database are shown with respect to inferred source depth. For offsets greater than ~ 5 km, depths are shown as a range of values which correspond to the best-fit depths from different modelling methods, source geometries and time periods in different cases. Displacements < 5 km from the associated edifice are shown as circles. Red symbols correspond to deformation attributed to magmatic processes, while blue symbols were attributed, at least in part, to hydrothermal processes. The examples in this figure are limited to those sources interpreted to be associated with magma storage of some variety, normally modelled as a sill, point source or ellipsoid. Volcano feature locations taken from GVP’s VOTW database. b. Illustration of generalised magmatic systems consistent with the prevalence of deformation sources at different lateral distances from and depths below a volcano. No vertical exaggeration
