In the meantime, however, they were implanted piezometers-albeit with great difficulty ( due to the need to reach the layers when there was aquifer ), as well as markers of land to see the movements of the landslide.

In addition, if at least initially technicians had been discussing on its real dimensions ( such as cubic meters of material landslide potentially moving ), since at least the year 1961 in which they were installed piezometers ( about 175m deep ), is objectively not credible believe that specialists did not have clear evidence that the landslide was interested in blocking a mass of large thickness ( depth ) and therefore of enormous volume, as piezometers, except the last meters of the number 4 ( according to other sources the two ), did not report breakage or deformation.
