Landslides are a major geologic hazard with estimated tens of deaths and $1–2 billion in economic losses per year in the US alone. The island of Puerto Rico experiences one or two large events per year, often triggered in steeply sloped areas by prolonged and heavy rainfall. Identifying areas susceptible to landslides thus has great potential value for Puerto Rico and would allow better managem...

abstract this survey accomplished for asessment and mechanism recognition of chenaran watershed landslide effective factors and its zonation based via lim model. primarily recognized effective factors, through studing and field survey and evaluated by landslide index method(lim) then based on their weight in model, landslide hazard zonation was done.then evaluated this model competence in zonat...

Availability of accurate and objective landslide susceptibility maps depicting zones defined on the basis of probability of occurrence of landslides is one of the critical inputs in assessing risk to property and lives in any mountainous region, particularly in the Himalayas. The aim of this study is to portray the usage of an in-house developed indigenous software, acronymmed as Landslide Susc...

nowadays, occurrence of mass movement in the northern forests ofiran, especially in the golestan province is turning to be a usual phenomenon. because of decay of vegetation cover, prediction of landslide occurrence will prevent its damages. landslide hazard zonation is a suitable way in this case. selection of the best model is a way to decrease costs and time. consequently, land slide hazard ...

it is very important to recognize the areas with high potential risk of landslide in order to resist that. in a case study, thirty three landslides have been observed in safarood watershed. the purpose of this study is to recognize factors and zonation of potential areas for landslide. this paper covers specific factors including lithology, fault, height, slope, direction, rainfall, soil, veget...

This paper presents a new approach of landslides zonation hazard studies, based on an integrated study of structural data along with geomorphological and external factors, in a hilly regions of Brazil, covered by a tropical humid rain-forest, called Serra do Mar. The Serra do Mar consists of a hilly region along the east coast of Brazil, with high slopes and many geological structures in a gnei...

In thepresent study,ArtificialNeuralNetwork (ANN)hasbeen implemented toderive ratingsof categories of causative factors, which are then integrated to produce a landslide susceptibility zonation map in an
