Campi Flegrei caldera is a good example of the most explosive volcanism on the Earth, a potential source of global catastrophes. Alike several similar volcanic areas (Yellowstone and Long Valley, USA; Santorini, Greece; Iwo Jima, Japan, etc.) its volcanic activity, i.e. eruptions and unrests, is dominated by physical mechanisms involving the strict interaction between shallow magma sources and geothermal systems. Campi Flegrei caldera, with respect to many similar area, has the advantage that the most interesting structural details and main volcanic features appear located at shallower depth, as testified by high temperatures measured at depth in past drillings, making it a natural candidate to understand, by deep drilling, the volcanic structure of calderas. The CFDDP project aims to understand, for the first time at calderas, the location and rehology of large residual magma chambers and the mechanisms of interaction between magma and aquifer systems to generate eruptions and unrests. The main targets of CFDDP are, in order of importance: the direct understanding of caldera volcanism; the installation of a deep borehole monitoring system; the development of innovative technologies for environment monitoring; the geothermal exploitation of Campi Flegrei and similar areas in Italy. CFDDP is then structured as a large multidisciplinary project, with a broader goal to establish, at Campi Flegrei, an international laboratory to study volcanic risk, environmental and technology issues, geothermal energy exploitation.
