On 18-21 June 1994, the Directorate Generalfor Science, Research and Development of the
European Convnission, jointly with the European Volcanology Project (EVOP) of the Science Foundation, convened an International Workshop at Act Castello
(Catania). Tiie aim of the workshop was to present and discuss the progress made in the
research projects financed by the EC Envirownent Research Programme in the field of
Volcanology. This part of the project is focused on the study of five European volcanoes,
selected as "Laboratory Volcanoes"
