Geophysical measurements in volcanic areas: Vulcano and Lipari

Southern Italy is characterised by several active volcanic regions like Mt. Vesuvio, Campi Flegrei, Etna and the Eolian Islands. Some of them are surrounded by some of the most densely populated areas in Europe like Napoli and Catania or are major targets for modern tourism, like Vulcano Island. Therefore in view of hazard mitigation it is very important to understand the structural and geological settings of these areas. In the frame of the European Community project TOMAVE (ENV4-CT-98-0697), different potential field methods were applied to investigate the physical structure of the volcanic areas, including airborne magnetics, VLF and gamma ray mapping at Mt. Vesuvio, Campi Flegrei and on the Islands of Vulcano and Lipari. In this paper we will focus mainly on the geoelectric, gravity and seismic research done on the Island of Vulcano on selected profiles. Moreover a 3d geoelectrical survey in a fumarolic area was conducted. In spring 2000 gravity measurements were carried out along the same profiles, covered in 1999 by geoelectrics and magnetics on the Island of Vulcano in the frame of an international co-operation with Japanese geophysicists from the Geological Survey of Japan.
