Self Introduction
My main research interests are focused on the origin, behaviour and role of volatiles
in magmatic-volcanic processes, with application to improved forecasting of
volcanic eruptions. Background scientific interest relies on the
pressure-related chemical and physical information on underground processes
carried by the magmatic gas phases, often in advance of eruptions, and their
temporal/causal relationship(s) with geophysical signals (seismic tremor, VLPs,
ground deformation, acoustics, etc.). Cross-correlated multidisciplinary
investigations are indeed required to image magma plumbing systems and better
understand how volcanoes work. During my 3-month visiting stay in ERI I’ll
contribute to the research/monitoring programs on Japanese volcanoes carried
out by the Volcanological Research Center, under the heading of Prof. M. Takeo.
Planned actions include novel measurements of the concentration and isotopic
composition (13C/12C) of carbon dioxide in volcanic
plumes from some Japanese volcanoes using a mobile (Delta Ray) mass
spectrometer, in collaboration with other researchers from GRC (Tokyo Univ.)
and JSG.
My staywill also include a teaching to graduate students in the first week of December on ‘Risk management and scientific communication during volcano emergencies’, in which I’ll present different case studies, compare with seismic risk management, and refer to existing systems and procedures at national and international level.
