The K method for estimating earthquake activity parameters and effect of the boundary uncertainty of the source region: discussion on the seismic zoning method

摘要

Two aspects pf a mew method, which can be used for seismic zoning, are introduced in this paper. On the one hand, the approach to estimate b value and annual activity rate proposed by Kijko and Sellevoll needs to use the earthquake catalogue. The existing earthquake catalogue contains both historical and recent instrumental data sets and it is inadequate to use only one part.
