Description:
Total CO2 output from soil gas and plume, discharged from the Stromboli Island, was estimated. The CO2
emission of the plume emitted from the active crater was estimated on the basis of the SO2 crater output
and C/S ratio, while CO2 discharged through diffuse soil emission was quantified on the basis of 419 measurements
of CO2 fluxes from the soil of the whole island, performed by using the accumulation chamber method.
The results indicate an overall output of ≅416 t day−1 of CO2 from the island. The main contribution to the
total CO2 output comes from the summit area (396 t day−1), with 370 t/day from the active crater and
26 t day−1 from the Pizzo sopra La Fossa soil degassing area. The release of CO2 from peripheral areas is
≅20 t day−1 by soil degassing (Scari area mainly). The result of the soil degassing survey confirms the persistence
of the highest CO2 degassing areas located on the North-East crater side and Scari area.
