Volcano tectonics a plumbing system and a deeper magma reservoir, Volcano-Tectonics is not restricted to the surface processes, but also includes any subsurface process in the host rock related to the shallower and deeper plumbing system of the volcano. The latter may be directly accessible in the eroded portions of active volcanoes or, more commonly, in extinct eroded volcanoes. The general aim of Volcano-Tectonics is to capture the shallower and deeper structure of volcanoes, establishing the overall stress-strain relationships between the magma and the host rock, to ultimately understand how volcanoes work in their regional context. This approach allows defining the dynamic
