Description:
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 associated
with 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 October
2010. 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 to
better understand the functioning of volcanic systems.
