This study used GIS as a tool to map storm-induced landslides from SPOT5 images. Digital elevation model (DEM) of 10m x 10m resolution was used to extract geomorphic landslide causative factors: slope gradient, slope roughness, tangential curvature, relative slope height, total slope height and wetness index etc. Digital geological map was used to extract geologic causative factors: lithology a...

Landslide inventories show that the statistical distribution of the area of recorded events is well described by a power law over a range of decades. To understand these distributions, we consider a cellular automaton to model a time and position dependent factor of safety. The model is able to reproduce the complex structure of landslide distribution , as experimentally reported. In particular...

We are designing a system to forecast rainfall-induced landslides in Italy. The system is based on a set of rainfall thresholds for the possible initiation of landslides, and an ensemble of small scale landslide hazard and risk zonations. Rainfall thresholds include existing and new, national, regional and local empirical thresholds of the intensity-duration (ID) and normalized-ID types. The ne...

Four custom fiber Bragg grating (FBG)-based sensors are developed to monitor an artificial landslide located in Nanjing, China. The sensors are composed of a rod and two FBGs. Based on the strength of the rods, two sensors are referred to as "hard sensors" (Sensor 1 and Sensor 2), the other two are referred to as "soft sensors" (Sensor 3 and Sensor 4). The two FBGs are fixed on each sensor rod ...

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...
