ESTIMATION OF STATIC COULOMB STRESS CHANGE AND STRONG MOTION SIMULATION FOR JIUZHAIGOU 7.0 EARTHQUAKE BASE ON SENTINEL-1 INSAR DATA INVERSION
InSAR Coulomb Stress Change Slip Inversion Strong Motion Aftershocks Slip Model Jiuzhaigou Earthquake
2018/5/15
On August 8, 2017, an earthquake of M 7.0 occurred at Jiuzhaigou. Based on the Sentinel-1 satellite InSAR data, we obtained coseismic deformation field and inverted the source slip model. Result...
ESTIMATION OF SURFACE DEFORMATION DUE TO PASNI EARTHQUAKE USING SAR INTERFEROMETRY
InSAR Surface Deformation Sentinet-1 Earthquake Pasni
2018/5/11
Earthquake cause ground deformation in sedimented surface areas like Pasni and that is a hazard. Such earthquake induced ground displacements can seriously damage building structures. On 7 February 20...

High temperature geothermal fluid Multi-component geothermometer optimization Geothermal gases Analogue
2018/3/23
his paper elaborates the chemical constituent change principles of deep geothermal fluid during the process of upward movement. It summarizes research methods of hydrochemistry, isotope and numerical ...
Maximum entropy estimation of values at Mt. Etna: comparison with conventional least squares and maximum likelihood results and correlation with volcanic activity
frequency-magnitude distribution maximim entropy method Mt. Etna
2015/10/8
The variations of the b coefficient in the frequency-magnitude relationship for earthquakes which occurred at Mt. Etna from 01/01/90 to 31/12/92 are analyzed; the completeness threshold for our earthq...
Fractal dimension confidence interval estimation of epicentral distributions
correlation dimension confidence interval seismicity
2015/9/30
Estimates of the fractal dimension of hypocentral distributions require evaluating the range of independent variables in which fractal parameters exhibit a power law. Systematic and accidental errors ...
Some preliminary results of a worldwide seismicity estimation: a case study of seismic hazard evaluation in South America
Seismicity maximum observed magnitude seismic moment seismic momente rate
2015/9/30
Global data have been widely used for seismicity and seismic hazard assessment by seismologists. In the present study we evaluate worldwide seismicity in terms of maps of maximum observed magnitude (M...
The impact of a and b value uncertainty on loss estimation in the reinsurance industry
Completeness seismic risk b-value average annual loss insurance
2015/9/30
In the reinsurance industry different probabilistic models are currently used for seismic risk analysis. A credible loss estimation of the insured values depends on seismic hazard analysis and on the ...
Earth modeling and estimation of the local seismic ground motion due to site geology in complex volcanoclastic areas
dynamic amplification factor seismic tomography pyroclastic rocks finite element method
2015/9/25
Volcanic areas often show complex behaviour as far as seismic waves propagation and seismic motion at surface are concerned. In fact, the finite lateral extent of surface layers such as lava flows, bl...
Estimation of seismic moments from local magnitudes and coda durations for the Cairo earthquake aftershocks recorded at Kottamyia (KEG) Broadband station
aftershocks seismic moment scaling
2015/9/17
The spectral analysis of fifty-five KEG VBB records from the October 12, 1992 Cairo earthquake source region
was performed to obtain the seismic moment. We obtained this parameter in turn to develop ...
Australian paleoseismology: towards a better basis for seismic hazard estimation
intraplate seismicity seismic hazard Australia paleoseismology
2015/9/16
Probabilistic seismic hazard analyses in Australia rely fundamentally on the assumption that earthquakes recorded in the past are indicative of where earthquakes will occur in the future. No attempt h...
Noise modelling and estimation of hyperspectral data from airborne imaging spectrometers
generalised Gaussian probability density function heavy-tailed distributions hyperspectral imagery linear regression noise modelling Visible InfraRed Scanner (VIRS-200)
2015/9/7
The definition of noise models suitable for hyperspectral data is slightly different depending on whether whiskbroom or push-broom are dealt with. Focussing on the latter type (e.g., VIRS-200) the noi...
