The changes of diffusive helium emissions rate were observed one month prior to the submarine eruption onset (12 October 2011) and the major increase preceded increases in seismic energy release during the volcanic unrest. Measured 3He/4He ratios in groundwaters from a well in El Hierro Island increased from 2–3 RA to 7.2 RA (RA = 3He/4He ratio in air) 1 month prior to the eruption onset, and reached a peak of 8.2 RA, indicating a dominant magmatic contribution to the dissolved gases in ground waters. 3He/4He values and diffusive helium emission studies have been extremely important for forecasting the onset of the volcanic unrest and subsequent volcanic eruption. An aseismic exsolution of magmatic gases from magma bodies beneath El Hierro Island through fractures and vertical permeability structures increased the diffusive helium emission rate prior to episodes of seismic energy release associated with the volcanic unrest.
