The Application of Different Geophysical Tomographic Techniques to the Study of Cultural Heritage Structures

B028 THE APPLICATION OF DIFFERENT GEOPHYSICAL TOMOGRAPHIC TECHNIQUES TO THE STUDY OF CULTURAL HERITAGE STRUCTURES 1 SUMMARY The Geophysical Section of the Dipartimento di Ingegneria Civile of the University of Pisa has been active in researches on the application of non-pervasive geophysical surveys on the masonry structures of historical buildings for more than fifteen years. As the main problem is to put in evidence the internal situation of structural elements (walls pillars etc.) the tomographic methods were used. We used both microseismic and geoelectric techniques. The results have been very interesting so we were encouraged to go on in three
