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 ...
Extreme value statistics and thermodynamics of earthquakes: aftershock sequences
Pareto and beta power laws cluster dimension frequency-magnitude regression laws order-statistics indipendence and clustering thermodynamics of aftershocks
2015/9/29
The Gutenberg-Richter magnitude-frequency law takes into account the minimum detectable magnitude, and treats aftershocks as if they were independent and identically distributed random events. A new m...
Extreme value statistics and thermodynamics of earthquakes: large earthquakes
Gutemberg-Richter Pareto laws
2015/9/28
A compound Poisson process is used to derive a new shape parameter which can be used to discriminate between large earthquakes and aftershock sequences. Sample exceedance distributions of large earthq...
ADDING VALUE TO SPATIAL DATA INFRASTRUCTURES THROUGH VISUAL ANALYTICS SERVICES FOR GEOMARKETING
Geovisualization spatial analytics service infrastructure ebusinesss models ,
2015/9/28
Spatial data infrastructures will shift from data catalogues to federated platforms for the development of low cost and low risk
applications. The GEOeBIZ project will contribute to this development...
A technical note on the bias in the estimation of the b-value and its uncertainty through the Least Squares technique
b-value Seismology Least Squares technique Synthetic-earthquake catalogs
2015/9/2
We investigate conceptually,
analytically, and numerically the biases in the estimation of the
b-value of the Gutenberg-Richter law and of
its uncertainty made through the least
squares technique...

Prof. Giulio Giorello is amongst the most prominent philosophers of science in Italy and in the world. He is currently Professor of the Philosophy of Science at the University of Milan, Director of th...
Empirical relationships of shear wave velocity,SPT-N value and vertical effective stress for different soils in Mashhad,Iran
Shear wave velocity Vertical effective stress Standard penetration test Downhole test, Empirical relations Mashhad Iran
2015/8/14
Shear wave velocity, Vs, is one of the important input parameters in seismic response analysis of the ground. Various methods have been examined to measure the soil Vs directly. Direct measurement of ...
Short-term changes in soil Munsell colour value, organic matter content and soil water repellency after a spring grassland fire in Lithuania
Short-term changes soil Munsell colour value organic matter content soil water repellency spring grassland fire Lithuania
2015/1/6
Fire is a natural phenomenon with important implications on soil properties. The degree of this impact depends upon fire severity, the ecosystem affected, topography of the burned area and post-fire m...
An inventory of topographic surface changes: the value of multi-temporal elevation data for change analysis and monitoring
DEM/DTM Geomorphology Change Detection SAR, Multitemporal Monitoring Accuracy Error
2014/7/23
Landscape change resulting from human activities continues to be a primary topic in geographic research. Many studies have focused upon human-induced changes in two dimensions, namely in land cover. H...
Order parameter fluctuations in natural time and b-value variation before large earthquakes
Order parameter fluctuations natural time b-value variation large earthquakes Geophysics
2012/5/29
Self-similarity may stem from two origins: the process' increments infinite variance and/or process' memory. The $b$-value of the Gutenberg-Richter law comes from the first origin. In the frame of nat...
Weather regime dependence of extreme value statistics for summer temperature and precipitation
Weather regime dependence extreme value statistics summer temperature
2009/10/30
Extreme Value Theory (EVT) is a useful tool to describe the statistical properties of extreme events. Its underlying assumptions include some form of temporal stationarity in the data. Previous studie...
Prediction of the Geomagnetic K Index Based on its Previous Value
geomagnetic forecasting geomagnetic variations K index
2009/6/9
The statistical behaviour of the geomagnetic K index is studied at two observatories in Finland:Nurmijärvi in the subauroral region and Sodankylä near the auroral region. Using data of 1953–...
