RAPID EXTRACTION OF LANDSLIDE AND SPATIAL DISTRIBUTION ANALYSIS AFTER JIUZHAIGOU Ms7.0 EARTHQUAKE BASED ON UAV IMAGES
Jiuzhaigou earthquake UAV object-oriented landslide extraction spatial distribution analysis
2018/5/14
Jiuzhaigou earthquake led to the collapse of the mountains and formed lots of landslides in Jiuzhaigou scenic spot and surrounding roads which caused road blockage and serious ecological damage. Due t...
Characteristics of flux-time profiles, temporal evolution, and spatial distribution of radiation-belt electron precipitation bursts in the upper ionosphere before great and giant earthquakes
Earthquake precursors particle precipitation wave particle interactions
2015/8/24
The analysis of energetic electron observations made by the DEMETER satellite reveals that radiation belt electron precipitation (RBEP) bursts are observed in general several (~1-6 days) before a larg...
A GIS-based application for volume estimation and spatial distribution analysis of tephra fallout: a case study of the 122 BC Etna eruption
Geographic Information System (GIS) Tephra fallout Volume estimation Etna
2015/8/18
In this study, we demonstrate the use of a geo-spatial information system for volume estimation of fallout deposits and for identification of syn-eruptive and post-eruptive depositional mechanisms. Fo...
Molecular Phylogenetic Diversity and Spatial Distribution of Bacterial Communities in Cooling Stage during Swine Manure Composting
Diversity Restriction Fragment Length Polymorphism
2016/5/18
Polymerase chain reaction-restriction fragment length polymorphism (PCR-RFLP) and subsequent sub-cloning and sequencing were used in this study to analyze the molecular phylogenetic diversity and spat...
The spatial distribution of star formation in the solar neighbourhood: do all stars form in dense clusters?
low-mass neighbours Spitzer Space Telescope
2014/12/20
We present a global study of low-mass, young stellar object (YSO) surface densities (ヒ) in nearby (<500 >pc) star-forming regions based on a comprehensive collection of Spitzer Space Telescope surveys...
Determination of an optimal interpolation technique to represent the spatial distribution of groundwater quality at urban and peri-urban areas of Proddatur, Y.S.R district, Andhra Pradesh, India
Ground water quality Geostatistics Multivariate analysis
2014/11/17
The preliminary aim of the present study is to analyze the spatial variability of ground water
quality parameters in Proddatur, India. The spatial variability and the GIS maps can be used
for mana...
Analysis of the spatial distribution between successive earthquakes in aftershocks series
Aftershocks Earthquake catalogs Spatial distribution Scaling
2015/8/18
The earthquake spatial distribution is being studied, using catalogs for different recent aftershock series. The quality of the available data, taking into account the completeness of the magnitude, i...

Slow-moving landslides (earthfl ows) can dominate hillslope sediment fl ux and landscape erosion in hilly terrain with mechanically weak, fi ne-grained rock. Controls on the occurrence of slow-moving ...
Using hilltop curvature to derive the spatial distribution of erosion rates
Using hilltop curvature derive the spatial distribution erosion rates
2014/5/20
Erosion rates dictate the morphology of landscapes, and therefore quantifying them is a critical part of many geomorphic studies. Methods to directly measure erosion rates are expensive and time consu...

Structure and spatial distribution of Ge nanocrystals subjected to fast neutron irradiation
Structure spatial distribution fast neutron irradiation
2010/11/23
The influence of fast neutron irradiation on the structure and spatial distribution of Ge nanocrystals (NC) embedded in an amorphous SiO2 matrix has been studied. The investigation was conducted by me...
The fractal spatial distribution of stars in open clusters and stellar associations
ISM structure open clusters and associations general stars formation
2010/11/11
The Interstellar Medium has a fractal structure, in the sense that gas and dust distribute in a hierarchical and self-similar manner. Stars in new-born cluster probably follow the same fractal pattern...
