Abstract The Hengduan Mountains Region (HMR) is one of the areas that experience most frequent geological hazards in China. However, few reports are available address hazard susceptibility region. This study developed six machine learning models to assess susceptibility. results show with medium and high as a whole account for almost 21% total area, while both 18% when it comes single landslide...

Hf isotope ratios measured in igneous zircon are controlled by magmatic source, which may be linked to tectonic setting. Over the 200-500 Myr periodicity of the supercontinent cycle - the principal geological phenomenon controlling prevailing global tectonic style - juvenile Hf signals, i.e. most radiogenic, are typically measured in zircon from granites formed in arc settings (crustal growth),...

Natural hazards of geological origin are one of major problem during heavy monsoons rainfall in Kelantan state, peninsular Malaysia. Several landslides occur in this region are obviously connected to geological and topographical features, every year. Satellite synthetic aperture radar (SAR) data are particularly applicable for detection of geological structural and topographical features in tro...

assessing seismic hazards involves specifying the likelihood, magnitude and location of earthquakes in a region. predicting the seismic hazards is the first step in reducing the impact of the damage caused by an earthquake.  in this study, to fully utilize all the known parameters which may possibly affect the occurrence of earthquakes (mb ≥ 4.5); a data-driven rule-extraction method called the...

Abstract Karaganda region is located on the most elevated central part of Kazakh Upland -Saryarka. This a peculiar and geomorphologically heterogeneous, sharply natural country. The paper considers conditions thematic factors physical-geographical, geological, engineering ecological-geological directions research, for preparation foundations compilation an engineering-geodynamic map assessment ...

The Environmental Protection Agency (EPA) and U.S. Geological Survey (USGS) initiated a two-year regional pilot survey in 2007 to develop, test, and validate tools and approaches to assess the condition of northern Gulf of Mexico (GOM) coastal wetlands. Sampling sites were selected from estuarine and palustrine wetland areas with herbaceous, forested, and shrub/scrub habitats delineated by the ...
