Objective Stratification of the lithosphere above the hot spot, height of the edifice resulting from magmatic discharge, ocean plate deflection assessed by the deepening of the Moho discontinuity under the island, phenomena of magma advection within the plate (sub-crustal underplating). Topography of structural interfaces in relation to lateral transfers of matter, assessing the volume of allochthonous terrains resulting from gravitational slides of volcanic matter on volcano's flanks, looking for continuity of the roof of the anterior ocean plate under the edifice, since this area can act as a decoupling zone.
