APPLICATION OF KRIGING METHOD TO ESTIMATIONS OF SEISMIC HAZARDS FOR EACH CONSTRUCTION SITE

The present paper reports some results of the investigation of practical application of an advanced Kriging method proposed by the authors to estimate seismic hazards. By adding only one new parameter, the proposed method can provide AIC 120 to 250 lower than that by an ordinary Kriging method, which corresponds to the random fields with 60 to 120 fewer explanatory variables. Also, the proposed method estimates the ranges of 150 to 700m while an ordinary method calculates those of 30 to 80m. As a result, the proposed method can practically estimate seismic hazards accurately for each construction site.
