Abstract

The intensity contour map can directly reflect the damage degree of an earthquake, and it is an image representation of a seismic influence field or ground motion intensity field. The Kriging interpolation method is an unbiased and optimal interpolation method, and this method can be used to rapidly process data of the sampling points and to build smooth intensity fields after earthquakes, as one of outputs of intensity rapid reporting, and consequently, the intensity contour map can serve earthquake emergency response. The article briefly describes the basic principle of Kriging interpolation method and puts forward the problems existing in experimental semivariograms in practice, and to solve the problem, the ground motion intensity attenuation relationship is used to re-match experimental semivariograms. The instrumental intensity data is assumed as regional variation, and it conducts Kriging interpolation computation of artificial models and actual earthquake cases, finally the calculation results are analyzed and discussed.
