This study was conducted in a joint project on physical volcanology between Gadjah Mada University Yogyakarta, Indonesia and the Institute of Geophysics, University of Stuttgart, Federal Republic of Germany.
The wavefields generated by strombolion activity are investigated using data from small-aperture (120-600 m) seismic arrays deployed on the north flank of Stromboli and data from seismic and pressure transducers set up near the summit crater.
A study of the product of hydromagmatic activity and their associated xenoliths has been made on the recent volcanic centres on the island of Flores and Faila, in the Azores, in order to define the geothermal context.
