Abstract

[automatically translated] The study of surface instability is of particular interest because very often this type of instability causes serious damage to human structures, and sometimes even loss of life. Despite the modest mass of mobilized soil, these landslides have a high hazard mainly due to their striking power; the most frequent damage affecting the roads and the related concrete or stone walls which are under intense lateral forces that cause tipping. In some cases it can also cause serious damage to buildings, breaking through the walls placed on the trajectory of the mass in motion, causing even the victims; examples of this occurred in the Alessandria area in 1977, in Valtellina in 1983, in Sarno in 1998 and, more recently, in the Ionian coast of Messina during the flood event of the October 2009. Numerous were the consequences of that event; it was, mainly, almost simultaneous primer of numerous landslides fluidization in a shell that funneled down the river system, have given rise to the muddy flows - debris by the high destructive power. It is not negligible, then, the importance of these phenomena of instability are of part of land use for agricultural and forestry purposes. From this stems the importance of the definition of models which capture the essential aspects of the processes that govern the surface instability and, to this end, it is essential to identifying their predisposing factors and triggering causes,
