introduction: landslides are amongst the most damaging geologic hazards in the world. they pose a threat to the safety of humankind lives as well as the environment, resources and property. compared with other natural hazards such as volcanic eruptions and floods, landslides cause considerable damage to human beings and massive economic losses (guzzetti, 2005). according to preliminary estimates...

In the last years a research project aimed at the assessment of the landslide hazard and susceptibility in the high Cordevole river basin (Eastern Dolomites, Italy) have been carried out. The hazard map was made adopting the Swiss Confederation semi-deterministic approach that takes into account parameters such as velocity, geometry and frequency of landslides. Usually these parameters are coll...

we use high-resolution electrical resistivity imaging to delineate the geometry of the landslide and discontinuity surface between slide mass and bedrock in roudbar region, ghazvin-rasht-anzali railway (the tunnel no. 2 at km. 108+825). the roudbar region characterized by high geological hazard and shows a complete panorama of mass movements. in this area, different landslide types predisposed ...

Landslides are significant natural hazards in many areas of the world. Mapping the areas that are susceptible to landslides is essential for a wise territorial approach and should become a standard tool to support land-use management. A landslide susceptibility map indicates landslide-prone areas by considering the predisposing factors of slope failures in the past. In the presented work, we ev...

Although typically small in terms of their spatial footprint, landslide hazards are relatively frequent in Northern Iran. In this study, we combine Geographic Information System (GIS), remote sensing and derive a landscape susceptibility map for Bostan Abad County, Iran. The main objective is an inventory evaluation and zonation of natural landslides. This 2685 square kilometer sized county is ...

Landslide triggered by earthquake or rainstorm often results in serious property damage and human casualties. It is, therefore, necessary to establish an emergency management system to facilitate the processes of damage assessment and decision-making. This paper has presented an integrated approach for mapping and analyzing spatial features of a landslide from remote sensing images and Digital ...

Landslides are considered as natural disasters that lead to many deaths and severe property damages worldwide. Therefore, it is necessary to investigate the effective factors in order to make urgent planning and to present management solutions for the sensitive regions. Massive movement of materials, such as a landslide, is one of the problematic hillslope processes in Javanrood located in the ...

introduction landslide is a geologic process that occurs over a wide variety of spatial and temporal scales in many mountainous landscapes. landslides have a correspondingly wide range of effects that depends strongly on their spatial pattern of occurrence and frequency and magnitude of movement. mass movements can be the dominant source of erosion responsible for the long-term geomorphic evolu...

Abstract Background NASA’s developers recently proposed the Sudden Landslide Identification Product (SLIP) and Detecting Real-Time Increased Precipitation (DRIP) algorithms. This double method uses Landsat 8 satellite images daily rainfall data for a real-time mapping of this geohazard. study adapts processing to face issues quality unavailability/gaps recent landslide events in west-Cameroon’s...
