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...

In the past, different approaches for automated landslide identification based on multispectral satellite remote sensing were developed to focus on the analysis of the spatial distribution of landslide occurrences related to distinct triggering events. However, many regions, including southern Kyrgyzstan, experience ongoing process activity requiring continual multi-temporal analysis. For this ...

Identification and mapping of landslide deposits are an intrinsically difficult and subjective operation that requires a great effort to minimise the inherent uncertainty. For the Staffora Basin, which extends for almost 300 km2 in the northern Apennines, three landslide inventory maps were independently produced by three groups of geomorphologists. In comparing each map with the others, large ...

This study focuses on landslide susceptibility mapping in the Daunia area (Apulian Apennines, Italy) and achieves this by using a multivariate statistical method and data processing in a Geographical Information System (GIS). The Logistic Regression (hereafter LR) method was chosen to produce a susceptibility map over an area of 130 000 ha where small settlements are historically threatened by ...

Landslide generated tsunamis are lesser-known yet equally destructive than earthquake tsunamis. Indeed, the highest tsunami wave recorded in recent history was generated by a landslide in Lituya Bay (Alaska, July 9, 1958) and produced runup in excess of 400 m. In this paper, we review the state of the art of landslide tsunami analytical modelling. Within the framework of a linearised shallowwat...

Landslide susceptibility mapping is one of the required activities in landslide prone area. This is intended to recognize the spatial probability of landslide as an action to minimize the upcoming impact. Landslide susceptibility map can be used as supporting information in spatial planning process as well, particularly in restricting landslide prone area as free of development zone . Currently...

a r t i c l e i n f o Multi-temporal ALOS/PALSAR images are used to automatically investigate landslide activity over an area of ~ 200 km by ~ 350 km in northern California and southern Oregon. Interferometric synthetic aperture radar (InSAR) deformation images, InSAR coherence maps, SAR backscattering intensity images, and a DEM gradient map are combined to detect active landslides by setting ...

Landslide hazards are one of the major natural hazards. It is difficult not only to get the integrated and accurate landslide datum but also to monitor and predict the landslide. This paper introduces a ground-based laser scanner application for the landslides monitoring and its experiment in Jingyang, Shaanxi province. The point cloud gained in the test region is processed by existing software...

A study of awareness of landslide hazards have been conducted among secondary school teachers. The survey focused on four schools which are located in landslide areas and questionnaire methodologies were adopted to collect data from each school. Guided and close-ended questionnaires were distributed to 60 teachers in four selected schools in Penang Island. From the survey, the results showed kn...
