WESSELOO, J.. Evaluation of the spatial variation of b-value. J. S. Afr. Inst. Min. Metall. [online]. 2014, vol.114, n.10, pp. 823-828. ISSN 2411-9717.
The estimation of the spatial variation of the b-value of the Gutenberg-Richter relationship is important for both the general interpretation of the mechanism of rock mass response and seismic hazard assessment. The interpretation of b-value as a parameter of rock mass response is discussed in this paper. The methods applied to evaluate the spatial variation of b-value and the algorithm for obtaining the magnitude of completeness and b-value for subsets of data are presented with some verification analyses. The algorithms presented enable the automation of a spatial evaluation of b-value.
