Landslide-susceptibility mapping is one of the most critical issues in Malaysia. These landslides can be systematically assessed and mapped through a traditional mapping framework that uses geoinformation technologies (GIT). The main purpose of this paper is to investigate the possible application of an artificial neural network model and its cross-application of weights at three study areas in...

Landslides are significant natural hazards in Turkey, second only to earthquakes with respect to economic losses and casualties. The West Black Sea region of Turkey is known as one of the most landslide-prone regions in the country. The work presented in this paper is aimed at evaluating landslide susceptibility in a selected area in the West Black Sea region using Artificial Neural Network (AN...

EXTENDED ABSTRACT      Recognition of effective factors on landslide occurrence in the area leads to an important set of solutions to control and take suitable actions upon this phenomenon. This paper aims at recognizing such factors and also landslide occurrence and zoning landslide hazard, using density area, Analytical Hierarchy Process and logistic regression, and also investigating the ac...

The steep topography of mountain landscapes arises from interactions among tectonic rock uplift, valley incision and landslide erosion on hillslopes. Hillslopes in rapidly uplifting landscapes are thought to respond to river incision into bedrock by steepening to a maximum stable or ‘threshold’ angle1–3. Landslide erosion rates are predicted to increase nonlinearly as hillslope angles approach ...

Landslides are a recurring phenomenon that disrupts the natural environment and causes yearly property damage, economic losses, fatalities. The damage is expected to increase due deforestation rates, population growth, agriculture, slope-building infrastructure expansion, global climate change. This study assesses susceptibility landslides through Weight of Evidence (WoE) Frequency Ratio (FR) m...

A systematic inventory of landslide events over the globe is valuable for estimating human and economic losses, quantifying the relationship between landslide occurrences and climate variations and for evaluating emerging global landslide prediction efforts based on remote sensing data. This study compiles a landslide catalog for rainfalltriggered events for several years, drawing upon news rep...

Landslides are the most recurrent and prominent disaster in Sri Lanka. Sri Lanka has been subjected to a number of extreme landslide disasters that resulted in a significant loss of life, material damage, and distress. It is required to explore a solution towards preparedness and mitigation to reduce recurrent losses associated with landslides. Artificial Neural Networks (ANNs) are now widely u...
