Abstract
The seismological and volcanological observations in the New Hebrides region during the last years have allowed the author to specify the structure and also the correlations between the deep seismicity and volcanic activity of this zone, hypothesis presented by the author since 1962.
From a statistical study made at the International Seismological Centre of Edinburgh one must conclude that there is a strong evidence in favour of a causative relationship between precursor intermediate focus earthquakes and subsequent eruptions. Then again these space and time correlations are tested by the success of volcanic eruptions forecasting.
Volcanism and seismicity in the upper mantle are connected by geographical, temporal and petrochemical correlations.
