Landslides triggered by rainfall can possibly be foreseen in real time by jointly using rainfall intensity-duration thresholds and information related to land surface susceptibility. However, no system exists at either a national or a global scale to monitor or detect rainfall conditions that may trigger landslides due to the lack of sufficient ground-based observing network in many parts of th...

The effect of landslide and its consequences always impact negatively on the inhabitants of a certain region or zone. The overall damage of socioeconomic structure and loss of human lives always a matter of concern. Numerous approaches of landslide susceptibility mapping, hazard analysis have been developed and in most cases remote sensing, Geographical Information System (GIS) remains the core...

landslides are the major natural hazard, causing significant damage to properties, lives and engineering projects in all mountainous areas in the world. in order to estimate the role of the landslides in erosion processes and evaluation of their risks, it is necessary to quantify landslides. this quantifying can be performed by applying the probability distributions that show the landslide size ...

This paper expands the previous efforts by other researchers to present a quantitative and deterministic approach for terrain analysis. This study evaluates both spatial and temporal factors contributing landslides utilizing Light Detection and Ranging (LiDAR) point clouds in conjunction with the frequency ratio model (PFR) than has previously been used in the Alborz Mountains. The study area i...

As the November torrential rains swept over coastal British Columbia, heralding the more reactive winter field season, I began to think about landslide hazards. Geoscientists are routinely asked to try to accurately identify hazard and risk based on limited knowledge. On the surface this appears to be a straight forward task, more realistically however, it involves specialized skills, experienc...

Landslides are a common hazard worldwide that result in major economic, environmental and social impacts. Despite their devastating effects, inventorying existing landslides, often the regions at highest risk of reoccurrence, is challenging, time-consuming, and expensive. Current landslide mapping techniques include field inventorying, photogrammetric approaches, and use of bare-earth (BE) lida...

A natural hazard is a geophysical, atmospheric or hydrological event (e.g., earthquake, landslide, tsunami, windstorm, flood or drought) that has the potential to cause harm or loss, while a natural disaster is the occurrence of an extreme hazardous event that impacts on communities causing damage, disruption and casualties, and leaving the affected communities unable to function normally witho...
