The aim of the present paper is to introduce a practical method to estimate the special distributions of ground motion, based on Kriging analyses using ordinary boring investigation data and one-dimensional earthquake response analyses. By this method, strong ground motions can be estimated accurately at a minimum costs. Because the Kriging analyses can also provide quantitatively the estimation errors, the low accurate estimation areas can be found at a glance in the all area. The sample analyses suggest us to utilize various countermeasures, which should be adopted due to the necessary, purposes, cost-performances, etc. The various best decision-makings can be performed toward the best countermeasures for earthquake disasters mitigation based on the introduced practical method.
