Abstract
A microtremor survey aiming to obtain information on subsoil structure was performed in the lower southwestern Etnean flank Sicily Italy The area is characterized by emissions of muddy and salty water which create specific pseudovolcanic edifices Recording sites were both randomly selected in the area and along two profiles Horizontaltovertical noise spectral ratio polarization and surface wave prospecting techniques were used The spectral ratios results set into evidence different frequency ranges that appear interesting to infer information on the subsoil structure The depth of the hydrocarbon reservoir was inferred through 1D modeling by using the information coming from the literature and experimental surveys Moreover a strongly directional effect suggests the existence of a NNWSSEoriented mud feeding dike
