“…External loading, another potential threat, was estimated by classifying it into land use and temporary extra surcharge load and their subjective probabilities were found to be 0.01 and 0.092, respectively. Similar events have also been observed by Mariappan [25] and Jaboyedoff et al [32]. The contributing events of land use and temporary extra surcharge load can be easily overcome by routine monitoring as compared to other non-maintenance issues.…”

“…Concerning other considered anthropic element, the statistical analysis highlighted significant linkage between road structures and landslides occurrence. Communication lines building and development induced a slope re-profiling, linked to the decrease of slope stability and landslides occurrence induced by cut and fill for road constrictions (Jaboyedoff et al 2016). We noticed that during the autumn heavy rainfall events, the pathways acted as a corridor, in which water and sediment transport have been gathered (Figure 8).…”

“…They alter the flow direction, concentration of run-off on the road surface and the subsurface interception by the cut-slope. All these aspects lead to the modification of the erosion pattern and the slope stability, supporting rainfall-induced landslides and mass movement (Borga et al 2004;Cevasco et al 2008;Tarolli et al 2013;Jaboyedoff et al 2016).…”

In the autumn of 2014, a series of rainfall events affected several sectors of the Liguria region, triggering many shallow landslides and causing three casualties and severe structural damages. The most intensely unstable area covered 385 km 2 , in which more than 1600 landslides have been identified. After these events, an airborne Light Detection and Ranging survey was carried out. The survey yielded a high-resolution digital terrain model (DTM) and aerial images that provided a means of identifying and mapping all the occurred landslides. The distribution analysis of slope instabilities highlighted the link with various human activities. In fact, the majority of the detected landslides occurred in man-modified areas. Geospatial and statistical analyses provided the identification of three main anthropic factors: terraces, their level of maintenance and road network. Moreover, they quantified their role in landslide triggering. These factors were not analysed as separate elements, but as a continuous process, overlapping in time, in man-made influence on landscape. The identification of such factors is a key element for a correct behaviour characterization of this landscape towards extreme flash floods events.

“…This type of reasoning tends to support the conclusions elaborated by [10][11][12][13][14][15] to better take into account the role of anthropogenic activities on landslides. However, if the approach seems promising, before we give some indications for the future development of the area, several methodological points and results require discussion.…”

“…Lastly, anthropogenic factors are rarely taken into account in slope stability analysis and mapping; as [10,11,15] point out, it is necessary to do so by answering the seven questions in Table 4. This summarizes the questions that can be asked before or during studies relative to slope stability.…”

Landslide hazard and risk assessment (LHA & LRA) in the French West Indies is a big challenge, particularly in Martinique, where several factors contribute to high slope sensitivity to landslides. This sensitivity is particularly due to volcanic ground, hurricane seasons, and growing pressure from urban development. Thus, to protect future goods and inhabitants and avoid increased slope sensitivity to landslide, it is necessary to analyze by different ways and complementary approaches the future planned areas. This research focuses on a site the City Council of 'La Trinité' wishes to develop. The goals consist of locating landslide-prone areas and providing some recommendations/indications for future projects. The site is characterized by a hilly topography alternating steep slopes, gentle slopes, and eroded areas and is located on a complex lithology (i.e., andesite, basalt, and weathered materials). By combining several approaches and techniques (geology, geomorphology, geophysics, and modeling), it is demonstrated that some areas are particularly susceptible to landslide, notably where colluviums are juxtaposed to highly weathered materials. The different documents produced, based on modeling and expert knowledge, combined with indications should allow the definition of new susceptibility classes, taking into account probable anthropic influence and development. Even if the temporal probability of the experimental documents is not taken into account, they help with refining knowledge of landslide-prone areas and different types of instability. The documents should be discussed with end users for future planning.
