Applied geochemistry to seismic-volcanic surveillance


Research objectives and content The main research objectives related to this research proposal is to investigate about geochemical precursory signatures related to seismic-volcanic crisis in active volcanes situated at different tectonic settings (oceanic volsanic island, island arc, oceanicand continental active margin zone). Monitoring active volsanoes to forecast volcanic eruptions remains a serious problem for the international scientific and political community. Among the reasons that om present understanding of the physical and Chemical processes leading to eruptions is limited, is the fact that adequate monitoring is conducted only at a very small number of active and potentially active volcanoes in the world (Scarca and Tilling, 1996). This problem is even bigger at active and large carders systems where recurrence of activity is low and the documentation of historical unrest is sparse (Newhall and Dzurisin, 1988). In addition, multi-disciplinary monitoring techniques for volcanic surveillance are not commonly applied at active volcanoes where monitoring is usually performed by conventional geophysical methods. The composition of gases released from volcanoes is a function of deep (magma type and vapor-melt separation during the generation and rise of the magmas) and shallow process (sewater mixing, meteoric water mixing, air mixing deposition of less gaseous species, mixing and combustion of organic matters, chemical reactions in the conduit, etc.); therefore, applied geochimical tools for volcano monitoring should account the role of both processes. Deep and shallow process affecting volcano degassing are closely related to the geo-tectonic framework of active volcanoes, thus, I am planning to perform geochemical monitoring research in active volcanoes which (1) do use only geophysical monitoring techniques, and (2) are situated in different geo-tectonic environments. I will focus my research work on active volcanoes in Papua New Guinea (island arc), one of the most active volcanic regions in the world, and in the Canary and Cape Verde Islands (oceanic volcanic island). Researchers from the Environmental Research Division at ITER will carry research activities in active volcanoes of Papua New Guinea in collaboration with Rabaul Volcano observatory and the Australia Geological Survey for the next 4 years. This research programme will allow me to investigate the use of geochemical monitoring techniques at Rabaul Karkar Manan and Ulawun volcanoes. In addition the actual research project of geochemical monitoring for the volcanic surveillance in the Canary and Cape Verde Islands in collaboration with the University of Tokyo (Japan) and the Instituto di Geocronologia e Geochimica Isotopica (Italia) will allow me to apply my research activities on those active volcanic regions.
Training content (objective, benefit and expected impact The main objective to apply for a Marie Curie Research Training Grant (category 20) is to be able to perform research activities related to active volcanoes for my Ph.D. degree with of the best applied geochemistry research groups in Europe, Insituto di Geocronologia e Geochimica Isotopica (Italy). This training will be tremendously beneficial for me since I am planning, after my research training period to return to my research group in the Canary Islands (Spain), Environmental Research Division at the Institute of Technology & Renewal Energy who is actually developing a geochimical monitoring network for the surveillance of active volcanoes in the Canary Islands (Spain), Cape Verde Islands, Papua New Guinea in collaboration with the Laboratory for Earthquake Chemistry at the University of Tokyo (Japan), Instituto Geocronologico e Geochimica Isotopica (Italia), Rabaul Volcano Observatory (Papua New Guinea), and Australian Geological Survey.
