5.1 Introduction

The timely identification of ground deformation at failure in areas at high hydrogeological risk has as a key prerequisite the definition of the distinctive character of the type of disruption that may develop on the slope. For this purpose, prior to any instrumental survey, the area subjected to potential hydrogeological instability should be identified and circumscribed by using the traditional geological-structural and geomorphological surveys. This distinction is very important since the dynamics of instability assume different behaviour in relation to the causes of activation or reactivation of the landslide . The characteristics will therefore be sought for the identification of several types of landslides belonging to the large group of hydrogeological instabilities in predominantly cohesive soils in order to simplify and make immediate the identification of areas at risk.

A first fundamental distinction is the following:(a)the slope may be subjected to a landslide of recent origin; recent landslides , or:
