Chemistry and amount of soil gas

What is it about?

Knowledge of how gas is transported within a volcano is rudimentary. We have proposed a model of how diffuse gases are transported through the flanks of a volcano. We performed laboratory experiments with major components of volcanic gas and some minor species that coexist with the major gases. The results of the gas transport experiments performed at laboratory scale agree with both the expected theoretical results and the results of gas monitoring in active volcanoes.

Why is it important?

We described the mass transfer process which triggers the time-dependent evolution of the chemistry of the soil gases. The combined approach of theoretical model and experiments, both in the laboratory and in the field, have great potential for shedding light on deeper processes within a volcano and for improving our volcano monitoring ability.
