Landslide is one of the major natural hazards the world is facing. It happens as a result of both man-made as well as natural factors. It causes severe effects on the environment as well as for the mankind. The main triggering factors of landslide are rainfall/snowfall, tectonic activities and human activities. There are many methods adopted for controlling landslides. The study was carried out...
Introduction Conclusions References
This paper presents preliminary results of the application of Persistent Scatterer SAR Interferometry for landslide mapping support. The PSI data were obtained basing on ERS-1/2 SAR data for the part of Carpathian Mountains in southern Poland. Careful PSI data processing allowed achieving very reliable results that were verified during the detailed field mapping. PSI data present their high app...
I develop a theory of dynamic responsiveness that suggests that parties that win elections choose candidates who are more extreme and parties that lose elections choose candidates who are more moderate. Moreover, the size of past victories matters. Close elections yield little change, but landslides yield larger changes in the candidates offered by both parties. I test this theory by analyzing ...
We use a dynamic finite-difference model to simulate martian landslides in the Valles Marineris canyon system and Olympus Mons aureole using three different modal rheologies: frictional, Bingham, and power law. The frictional and Bingham modes are applied individually. Fluidized rheology is treated as a combination of frictional and power-law modes; general fluidization can include pore pressur...
Geophysical survey methods bring information on the rock environment in real time, i.e. already during the geophysical survey. A geologist or a geotechnician provides such obtained information to a designer for the purpose of designing and implementation work at construction sites. Also, information on the effect of the rock environment or its properties (changing with time) on stabilization wo...
Citation: Juanico DEO (2016) Commentary: The impact of climate change on landslides in southeastern of high-latitude permafrost regions of China. Front. Earth Sci. 4:11. Permafrost melting could trigger geomorphic change processes on the Earth's surface, such as landslides, ground subsidence, and erosion. Although permafrost accounts for a minute portion of the Earth's total water content, it o...
Background and objective: Landslide susceptibility zoning using different methods is one of the landslide management strategies. The purpose of this study is to evaluate the landslides susceptibility in the Bar watershed in Khorasan Razavi province using the support vector machine (SVM) algorithm. Method: First, the landslide layer of the area was corrected through field visits and Google Earth...
Watersheds are changed positively or negatively as biotic and abiotic factors in natural circumstances impact them. Landslides, as a physical factor, one of the negative consequences on these catchments. Masoleh watershed, in North of Iran, is one of the susceptible areas to explode the natural landslides. In other to landslide hazard zonation, the Dempster-Shafer model is which is used has 14 ...
