The results of investigations carried out on volcanic gases are reported. A brief description is given of the differentiated sampling and analytical procedures used for acid, condensable and non-condensable gases. The fumaroles at the crater are characterized by different temperatures but substantially uniform composition, indicating a common genetic process; in addition to gaseous species peculiar to a magnetic environment, waters of marine origin appear to be recycled into the feeding paths of these manifestations. The composition of the bubbling gases at the beach and in mud pools is considered to be the result of the flow of gaseous species of deep origin through shallow and surface aquifers; acid gases are preferentially absorbed and the concentrations of slightly soluble species, such as H/sub 2/, N/sub 2/, O/sub 2/ and CH/sub 4/, are considerably enhanced.
