Structural, morphological and ground deformation studies suggest that the eastern flank of Mt. Etna (eastern Sicily) is spreading seaward.  According to the deep-seated spreading model, both the volcanic edifice and its uppermost basement are spreading eastwards because of magma inflation processes related to a dike complex located at a depth between the summit craters and the Valle del Bove.

In this work, in order to test the deep-seated spreading model, we carried out a finite element simulation performed with the COMSOL Multiphysics software.
