Figure 4
3D representation using Blender (version 2.78c; www.blender.org) of the comparatively low densities found between the Vesuvius cone and Mt. Somma. The rendered orange surface indicates a body with a density above 2370 kg m−3 and the denser red body a density above 2440 kg m−3. The present surface topography is represented by a black mesh and a satellite image from the same point of view is provided in the inset (Imagery ©2017, Map data ©2017 Google).
