Updating procedure for estimating spatial distribution of earthquake ground motion indices

| 抄録（英）： |
This paper presents an updating procedure for efficiently estimating the spatial distribution of earthquake ground motion indices when a one or more observed data are sequentially available. The update equations of simple kriging are derived. Numerical results show that as the number of observed data increases, better estimates are recursively obtained, and at the same time the error variances reduce. It is found that this procedure offers a significant computational saving when compared to a naive kriging implementation.
