“…The understanding of the stress orientation will improve the knowledge of deformation mechanisms, which is crucial for the implementation of a viable monitoring system. Irfan (1999), Revellino et al (2010), Grelle et al (2011), Aucelli et al (2013), Prakash et al (2015) have reported structurally-controlled landslides. Investigation of the landslides revealed that the geo-structural settings predisposed the slopes to factors triggering mass movements, which is consistent with Fookes and Wilson (1966), Zaruba andMencl (1969), andVarnes (1978).…”

Background: Structures such as faults, joints and fractures of diverse patterns have acted as precursors of several slope instability cases within the Benue Trough Nigeria. In some cases, the structures by their nature weakened and also created avenues that streams took advantage to further destabilize the rock slopes. In other cases, structure orientation played significant roles in the mobility and eventual runout distance of debris flow and avalanches in the region. Detailed field-based structural, fracture and paleostress analyses were therefore carried out to determine the fractural patterns that correlate to reported instability and landslide cases in the region; and to produce models that reveal areas with heightened risk.

“…This setting facilitates the superficial water streaming, increasing material erosion and transport downslope. In such a case, the evolved types show lateral secondary landslides creating a multi-source system (Revellino et al, 2010). …”

“…This background is representative of the morphological evo- lution of slopes in the Benevento province (Southern Italy), where slow-moving landslides are particularly widespread in some areas, giving to the region a distinctive feature. Surveys and multitemporal analyses have shown that most of these instabilities are structurally-controlled or directly connected to the local geological setting both in the source area and along the channel or the accumulation area (Revellino et al, 2010).…”

“…Revellino et al (2010) grouped these deposits into five successions distinguished by likely lithotechnical homogeneity, or more specifically, by similar lithotypes according to their lithology and engineering-geological/geomechanical features. With regards to the area investigated in this paper, two of the five groups of sequences were found; each of them includes more than one lithotechnical unit.…”

“…;1985), stratigraphic or tectonic contacts between rocks with different geomechanical properties, and zones of intense fracturing linked to the presence of axes of folds and faults are all geological conditions at the basis of structural control (e.g. Guzzetti et al, 1996;Irfan, 1998;Scheidegger, 1998;Cruden, 2000;Martino et al, 2004;Margielewski, 2006;Prager et al, 2009). The definition of these elements at different scales plays a fundamental role in understanding the landsliding mechanism.…”

Abstract. Litho-structural control on the spatial and temporal evolution of landslides is one of the major typical aspects on slopes constituted of structurally complex sequences. Mainly focused on instabilities of the earth flow type, a semi-quantitative analysis has been developed with the purpose of identifying and characterizing litho-structural control exerted by bedding on slopes and its effects on landsliding. In quantitative terms, a technique for azimuth data interpolation, Non-continuous Azimuth Distribution Methodological Approach (NADIA), is presented by means of a GIS software application. In addition, processed by NADIA, two indexes have been determined: (i) , aimed at defining the relationship between the orientation of geological bedding planes and slope aspect, and (ii) C, which recognizes localized slope sectors in which the stony component of structurally complex formations is abundant and therefore operates an evolutive control of landslide masses. Furthermore, some Litho-Structural Models (LSMs) of slopes are proposed aiming at characterizing recurrent forms of structural control in the source, channel and deposition areas of gravitational movements. In order to elaborate evolutive models controlling landslide scenarios, LSMs were qualitatively related and compared with and C quantitative indexes. The methodological procedure has been applied to a lithostructurally complex area of Southern Italy where data about azimuth measurements and landslide mapping were known. It was found that the proposed methodology enables the recognition of typical control conditions on landslides in relation to the LSMs. Different control patterns on landslide shape and on style and distribution of the activity resulted for each LSM. This provides the possibility for first-order identification to be made of the spatial evolution of landslide bodies.
