landslides are among important mass movements of a great interest for earth scientists. this is due to their importance in land use and decision-making in rural and urban areas. survey of old landslides to determine their behavior has important bearing on the study of new ones. seimareh grand landslide is one of the oldest and the most attractive phenomenon that has been the subject of concern ...
This paper presents an integrated approach to landslide research based on remote sensing and sensor networks. This approach is composed of three important parts: (i) landslide susceptibility mapping using remote-sensing techniques for susceptible determination of landslide spots; (ii) scaled-down landslide simulation experiments for validation of sensor network for landslide monitoring, and (ii...
In this research, machine learning algorithms were compared in a landslide-susceptibility assessment. Given the input set of GIS layers for the Starča Basin, which included geological, hydrogeological, morphometric, and environmental data, a classification task was performed to classify the grid cells to: (i) landslide and non-landslide cases, (ii) different landslide types (dormant and abandon...
Landslide is one of the common hazards occurring globally and Malaysia is not spared as well. Over the past four decades, Malaysia has played host to a number of landslide incidents, resulting in significant loss of lives and damage to property. The magnitude of landslide destruction is quite high in Malaysia. A survey has been carried out on 143 respondents in selected areas. This paper presen...
The main purpose of this paper is to present some potential applications of sophisticated data mining techniques, such as artificial neural network (ANN) and boosted tree (BT), for landslide susceptibility modeling in the Yongin area, Korea. Initially, landslide inventory was detected from visual interpretation using digital aerial photographic maps with a high resolution of 50 cm taken before ...
Current landslide hazard analysis does a poor job of informing the planning process for forest operations in that landslide models provide maps of landslide hazard instead of quantitative measure of landslide impact. Other aspects of forest management planning (such as road surface erosion) provide quantifiable estimates of impacts such as tons of sediment delivered to the stream. This paper ou...
The landslide is one of serious natural disasters in many countries around the world especially on highland area during the rainy season. Therefore, the early warning system which can predict the occurrences of landslide on hazard areas is seriously required for preventing damage to life and assets. Three-dimensional models are also needed to simulate landslide areas for prediction of the overa...
Landslide susceptibility map is one of the study fields portraying the spatial distribution of future slope failure susceptibility. This paper deals with past methods for producing landslide susceptibility map and divides these methods into 3 types. The logistic linear regression approach is further elaborated on by crosstabs method, which is used to analyze the relationship between the categor...
In this paper, bivariate statistical analysis modeling was applied and validated to derive a landslide susceptibility map of Peloponnese (Greece) at a regional scale. For this purpose, landslide-conditioning factors such as elevation, slope, aspect, lithology, land cover, mean annual precipitation (MAP) and peak ground acceleration (PGA), and a landslide inventory were analyzed within a GIS env...
This review presents modelling techniques and processes that govern landslide tsunami generation, with emphasis on tsunamis induced by fully submerged landslides. The analysis focuses on a set of representative examples in simplified geometries demonstrating the main kinematic landslide parameters influencing initial tsunami amplitudes and wavelengths. Scaling relations from laboratory experime...
