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...
A LANDMARK EXTRACTION METHOD ASSOCIATED WITH GEOMETRIC FEATURES AND LOCATION DISTRIBUTION
Landmark Extraction Geometric Features Crevice Horizon Segmentation Voronoi Diagram
2018/5/16
Landmark plays an important role in spatial cognition and spatial knowledge organization. Significance measuring model is the main method of landmark extraction. It is difficult to take account of the...
Importance of damage data from destructive earthquakes forseismic microzoning Damage distribution during the 1923 Kanto,Japan,earthquake
seismic microzoning damage data
2015/9/25
To verify the results of seismic microzoning and to improve techniques, the damage data of past destructive earthquakes is an important key reference. The damage data of the 1923 Kanto, Japan, earthqu...
Bayesian analysisof a probability distribution for local intensity attenuation
Beta distribution binomial distribution power law random intensity decay validation
2015/9/15
Intensity attenuation and its variation as a function of the distance and earthquake size is still a critical issue in evaluating seismic hazard. We present a method that allows us to incorporate addi...
Influence of strong electromagnetic discharges on the dynamics of earthquakes time distribution in the Bishkek test area (Central Asia)
seismic regime strong electrical discharges non-linear dynamics
2015/9/8
From 08/01/1983 to 28/03/1990, at the Bishkek ElectroMagnetic (EM) test site (Northern Tien Shan and Chu Valley area, Central Asia), strong currents, up to 2.5 kA, were released at a 4.5 km long elect...
AIDA–Seismic data acquisition,processing,storage and distribution at the National Earthquake Center,INGV
Earthquake location Moment tensor Magnitude
2015/8/26
On May 4, 2012, a new system, known as the AIDA (Advanced Information and Data Acquisition) system for seismology, became operational as the primary tool to monitor, analyze, store and distribute seis...
Static stress transfer from the May 20,2012,M 6.1 Emilia-Romagna (northern Italy) earthquake using a co-seismic slip distribution model
Stress Transfer Slip distribution Italy
2015/8/26
We model the static stress transfer for the May 2012 northern Italy earthquakes, assuming that failure of the crust occurs by shear. This allows the mechanics of the process to be approximated by the ...
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...
Modelling complex geological circular data with the projected normal distribution and mixtures of von Mises distributions
Circulation data earth science statistical description structural geology circulation data set
2015/1/6
Circular data are commonly encountered in the earth sciences and statistical descriptions and inferences about such data are necessary in structural geology. In this paper we compare two statistical d...
Segmentation of the Izu-Bonin and Mariana slabs based on the analysis of the Benioff seismicity distribution and regional tomography results
Model the mantle mariana arc travel around the world
2015/1/5
We present a new model of P and S velocity anomalies in the mantle down to a depth of 1300 km beneath the Izu-Bonin and Mariana (IBM) arcs. This model is derived based on tomographic inversion of glob...
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...
Fluid transfer and vein thickness distribution in high and low temperature hydrothermal systems at shallow crustal level in southern Tuscany (Italy)
Hydrothermal systems Vein thickness distribution Transmissivity Tuscany
2015/8/17
Geometric analysis of vein systems hosted in upper crustal rocks and developed in high and low temperature hydrothermal systems is presented. The high temperature hydrothermal system consists of tourm...
Convergence of the frequency-size distribution of global earthquakes
frequency-size distribution global earthquakes
2014/5/19
The Gutenberg-Richter (GR) frequency-magnitude relation is a fundamental empirical law of seismology,but its form remains uncertain for rare extreme events.Here, we show that the temporal evolution of...
