An Improved Method for Estimating the Seismic Intensity Based on Grey System Theory

When a big earthquake happens, the reliable estimation of the earthquake damage within a short time is very important for the government to allocate the rescue personnel and supplies. A new method to estimate the seismic intensity rapidly based on the grey system theory is proposed in this paper. The seismic intensity is closely related to the ground motion parameters, which indicates it can be obtained simultaneously by knowing the ground motion parameters. Through the preliminary theory and experiment analysis, the method could be used to estimate the seismic intensity accurately with less calculation and strong real time characteristics.
