Abstract
Within the "Energetics Special Project", a Geothermal Energy Subproject sponsored by National Research Council, ISMES carried out a geophysical investigation in the Bolsena lake (Central Italy), during 1988. The project included a high resolution seismic reflection survey and a magnetic survey, and was followed by a preliminary interpretation of the data. Recently, new volcanological and geothermal studies carried out by University of Pisa and National Power Electric Company (ENEL) brought to the definition of a new stratigraphic scheme based on surface and boreholes data, and to the outlining of the presence and role of a complex calderic structure in the area. These new results provided additional information for the interpretation of the seismic data.
