Through studies on the historical data of the two historical strong earthquakes in Linfen region, the characteristics of earthquake disaster distribution are summarized, and the actual isoseismal are drawn. By comparison of theoretic isoseismal maps obtained from different attenuation relationship models, the most suitable model and its modification part for different magnitudes in this region are determined. Using the spatial analysis function of GIS techniques, the more visual system of earthquake disaster prediction and evaluation is realized.
