Abstract

Here, we report the first continuous data of geochemical parameters acquired directly from the active summit crater of Vulcano. This approach provides a means to better investigate deep geochemical processes associatedwith the degassing system of Vulcano Island. In particular, we report on soil CO2 fluxes from the upper part of Vulcano,a closed-conduit volcano, from September 2007 to October2010. Large variations in the soil CO2 and plume SO2 fluxes(order of magnitude), coinciding with other discontinuous geochemical parameters (CO2 concentrations in fumarole gas) and physical parameters (increase of shallow seismic activity and fumarole temperatures) have been recorded.The results from this work suggest new prospects for strengthening geochemical monitoring of volcanic activity and for improving the constraints in the construction of a“geochemical model”, this being a necessary condition tobetter understand the functioning of volcanic systems.
