Resistivity Imaging of Great Mass Movements - Two Examples from Northeastern Italy

P055 RESISTIVITY IMAGING OF GREAT MASS MOVEMENTS – TWO EXAMPLES FROM NORTHEASTERN ITALY Abstract 1 In the present work the results of a large geophysical survey using electrical resistance tomography (ERT) technique carried out over two different mass movements in Northeastern Italy will be presented and discussed. At one site the internal structure of a large debris flow has been investigated while in the other the depth to the slipping surface was estimated. The depths in hand exceeded one hundred meters below the ground surface; despite this the resolution of the method was sufficient to achieve relevant information not only
