The project objective is to organize an itinerant exposition about volcanic events in the three partner's archipelagos. For this, it is necessary to select geologic, geophysics and geo-chemistries information about some paradigmatic islands (Faial, Pico, S. Jorge, Terceira, S. Miguel - in the Azores Archipelago; Porto Santo - Madeira Archipelago; Lanzarote and Tenerife - Canaries Archipelago) and to fill some important gaps in knowledge. With this project, we intend to develop, with interdisciplinary and interregional teams, to promote some exchange that will combine these three archipelagos. The collected data will be available to the scientific community and to the general public through a web site.
