Multidisciplinary Approach to a Recovery Plan of Historical Buildings
Figure 7
Seismic refraction profiles ((a), (c) and (e)) detect three layers, the first two (A1 and A2) related to Unit A and the third to Unit B drilled by boreholes; LV indicates low-velocity zones. Electrical resistivity tomography profiles ((b), (d) and (f)) detect four layers, the first two related to Unit A, the third to Unit B, and the fourth (C) to a non drilled shale layer. LD indicates lateral discontinuity of marl formation. Profile locations appear in Figure 5.
