This paper describes the seismic activity of Vulcano - an active volcano of the Aeolian Islands group - from 1977 to 1980. Two main swarms of low energy seismic events are recognizable on the basis of the entire set of data. The events, localized very near the crater of Vulcano where a fumarole field is present, have been classified into two classes:i) very shallow events (as far as 1 km in depth); andii) deeper events (as far as 3 km in depth). Double events and small earthquakes localized on the rim of the old caldera have also been recorded in a little percentage. The seismic events of Vulcano can be attributed to an intensive fumarolic activity.
