Abstract
We present the results of a study concern- ing the definition of the main structural linea- ments and the dynamic processes characterising the shallower crustal portion of the south-east- ern sector of the Mt.Etna by electric-type geo- physical methods. At this end, using the self- potential and the geoelectrical techniques, a geophysical exploration was performed in a test-site (Cisternazza-Montagnola area) interest- ed by the eruption events of July-August 2001. In particular, a self-potential survey, in an area of about 2 km2, and a geoelectrical tomography, along a profile 1200 m long, have permitted to model the buried volumes down to a depth of about 300 m below ground level. The presence of low resistivity and high charge occurrence probability values in the central portion of the investigated area, to a depth of about 150 m b.g.l., seems to indicate the occurrence of a shal- low groundwater flow.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
