From: Progressive underplating of mafic material at mid-crustal depth beneath Ischia volcano, Italy

3D view and topographic height are drawn in panel a after Acocella and Funiciello16. b The main 3D elements are schematically represented to visualize their respective location. From surface to bottom (down to 20 km) as follows: the N110° striking fault, the anisotropic crystal mush, and the mafic underplating.
