Impact of mapping errors on the reliability of landslide hazard maps
mapping errors landslide hazard maps
2009/12/9
Identification and mapping of landslide deposits are an intrinsically difficult and subjective operation that requires a great effort to minimise the inherent uncertainty. For the Staffora Basin, whic...
Flow-type failures in fine-grained soils:an important aspect in landslide hazard analysis
Flow-type failures fine-grained soils important aspect landslide hazard analysis
2009/12/8
Forecasting the possibility of flow-type failures within a slow-moving landslide mass is rarely taken into account in quantitative hazard assessments. Therefore, this paper focuses on the potential tr...
A methodological approach to characterise Landslide Periods based on historical series of rainfall and landslide damage
methodological approach Landslide Periods historical series landslide damage
2009/12/8
Landslide Periods (LPs) are defined as periods, shorter than a hydrological year, during which one or more landslide damage events occur in one or more sectors of a study area. In this work, we presen...
On the influence of temporal change on the validity of landslide susceptibility maps
temporal change validity landslide susceptibility maps
2009/12/8
The consideration of non-stationary landslide causal factors in statistical landslide susceptibility assessments is still problematic. The latter may lead to erroneous model predictions, especially in...
A web-based GIS for managing and assessing landslide data for the town of Peace River,Canada
web-based GIS managing and assessing landslide data town of Peace River
2009/12/8
Assessment of geological hazards in urban areas must integrate geospatial and temporal data, such as complex geology, highly irregular ground surface, fluctuations in pore-water pressure, surface disp...
Groundwater processes in a complex landslide,northern Apennines,Italy
Groundwater processes complex landslide northern Apennines
2009/12/8
The hydrogeological characteristics of roto-translational slides in flysch are complex, due to the inherent anisotropy and heterogeneity of rock masses and related deposits. The paper deals with the h...
Combined rock slope stability and shallow landslide susceptibility assessment of the Jasmund cliff area (Rügen Island,Germany)
rock slope stability shallow landslide susceptibility assessment Jasmund cliff area
2009/12/8
In this contribution we evaluated both the structurally-controlled failure susceptibility of the fractured Cretaceous chalk rocks and the topographically-controlled shallow landslide susceptibility of...
Evaluation of a preliminary satellite-based landslide hazard algorithm using global landslide inventories
preliminary satellite-based landslide hazard algorithm global landslide inventories
2009/12/8
Most landslide hazard assessment algorithms in common use are applied to small regions, where high-resolution, in situ, observables are available. A preliminary global landslide hazard algorithm has b...
Geotechnical and geochemical investigations of the Marquês de Pombal landslide at the Portuguese continental margin
Geotechnical and geochemical investigations Pombal landslide Portuguese continental margin
2009/12/3
The continental slope of the SW Portuguese continental margin is a geomorphologically diverse, tectonically active area with active faulting, canyon formation and mass wasting. Along the Marquês de Po...
Landslides are natural hazards occurring in response to triggers of different origins, which can act with different intensities and durations. Despite the variety of conditions that cause a landslide,...
Probability distributions of landslide volumes
Probability distributions landslide volumes
2009/10/30
We examine 19 datasets with measurements of landslide volume, VL, for sub-aerial, submarine, and extraterrestrial mass movements. Individual datasets include from 17 to 1019 landslides of different ty...
The Relationship Between Geology and Landslide Hazards of Atchison,Kansas,and Vicinity
Relationship Geology Landslide Hazards
2009/10/20
Landslides along the Missouri and Kansas rivers will affect existing structures and potential development in the Kansas City metropolitan area. A pilot landslide-mapping project was conducted in the v...

Optimal estimator for assessing landslide model performance
success rate modified success rate
2009/5/15
The commonly used success rate (SR) in evaluating cell-based landslide model performance is based on the ratio of successfully predicted landslide sites over total actual landslide sites without consi...
