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 ...
A review and new insights on the estimation of the b-valueand its uncertainty
b-value seismology statistical methods synthetic-earthquake catalogs
2015/9/17
The estimation of the b-value of the Gutenberg-Richter Law and its uncertainty is crucial in seismic hazard studies,
as well as in verifying theoretical assertions, such as, for example, the universa...
Uncertainty analysis for seismic hazard in Northern and Central Italy
seismic hazard uncertainty analysis Italy
2015/9/10
In this study we examine uncertainty and parametric sensitivity of Peak Ground Acceleration (PGA) and 1-Hz
Spectral Acceleration (1-Hz SA) in probabilistic seismic hazard maps (10% probability of exc...
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...
Interpretative modelling of a geological cross section from boreholes: sources of uncertainty and their quantification
Geology geological section tertiary London clay
2015/1/6
We conducted a designed experiment to quantify sources of uncertainty in geologists' interpretations of a geological cross section. A group of 28 geologists participated in the experiment. Each interp...
Mapping the climate: guidance on appropriate techniques to map climate variables and their uncertainty
Mapping the climate ppropriate techniques
2014/12/11
Maps are a crucial asset in communicating climate science to a diverse audience, and there is a wealth of
software available to analyse and visualise climate information.
Accounting for prediction uncertainty when inferring subsurface fault slip
Inverse theory Probability distributions Earthquake source observations
2014/4/9
This study lays the groundwork for a new generation of earthquake source models based on a general formalism that rigorously quantifies and incorporates the impact of uncertainties in fault slip inver...
UNCERTAINTY MANAGEMENT IN SEISMIC VULNERABILITY ASSESSMENT USING GRANULAR COMPUTING BASED ON COVERING OF UNIVERSE
Seismic Vulnerability Assessment Granular Computing Model, Multi Criteria Decision Making
2014/4/24
Earthquake is an abrupt displacement of the earth's crust caused by the discharge of strain collected along faults or by volcanic
eruptions. Earthquake as a recurring natural cataclysm has always be...
A non-linear and stochastic response surface method for Bayesian estimation of uncertainty in soil moisture simulation from a land surface model
response surface method Bayesian estimation soil moisture simulation land surface model
2009/11/11
This study presents a simple and efficient scheme for Bayesian estimation of uncertainty in soil moisture simulation by a Land Surface Model (LSM). The scheme is assessed within a Monte Carlo (MC) sim...
State dependent predictability:impact of uncertainty dynamics,uncertainty structure and model inadequacies
State dependent predictability uncertainty dynamics uncertainty structure model inadequacies
2009/11/11
The implications of state dependent, finite time error growth has been studied using singular values in a chaotic 2-dimensional map. Earlier studies have demonstrated the superiority of the singular v...
Exact Uncertainty Principle and Quantization: Implications for the Gravitational Field
Exact Uncertainty Principle and Quantization the Gravitational Field
2010/10/14
The quantization of the gravitational field is discussed within the exact uncertainty approach. The method may be described as a Hamilton-Jacobi quantization of gravity. It differs from previous appro...
