In this paper, we propose a methodology for validating landslide susceptibility results in the Pinggu district (Beijing, China). A landslide inventory including 169 landslides was prepared, and eight factors correlated to landslides (lithology, tectonic faults, topographic elevation, slope gradient, aspect, slope curvature, land use, and road network) were processed, integrating two techniques,...

The Linxia Basin is located in the transition zone between Qinghai–Tibet Plateau and Loess China. Collapse–landslide–debris flow geological disasters are particularly prevalent this region. Taking a debris that occurred Zhangjiayuan gully, Dongxiang County, as an example, characteristics formation mechanism were studied through field investigation remote sensing interpretation methods. hazard z...

Many health studies use aggregate data such as the means or totals for areal units or zones when individual level data are not available. An ecological analysis using these data typically produces estimates that differ from those obtained using the corresponding individual level analysis. This is due to the modifiable area unit problem (MAUP) whereby the results of the analysis depend on the sc...

â â â  the study area is located in the wes of iran, the southwest part of “bisetoon” mountain, and kermanshah city. it covers an area of ~1489 km2 . landslide have been the most common natural phenomenon in the area, which usually is triggered by heavy rainfall and seismic activities. although there are few active landslides in the area, but they are serious threats for population and infr...

In the framework of the on-going SLAM project (Service for Landslide Monitoring), funded by the European Space Agency (ESA) the Permanent Scatterers processing and the analysis of high resolution images (e.g. SPOT5) have been performed at a basin scale, on the whole territory of the Arno River basin (Central Italy). The project aims at the development of a service based on the integration of EO...
