Rapid Assessment of Disaster Loss and Spatial Distribution of Intensity Residuals in Linfen Area

Abstract

Through the probability analysis of seismic hazard analysis, the probability distribution results of different intensity in each township of Linfen area are given. Through analysis, it is concluded that the probability of occurrence of high-intensity impact in the Linfen basin is higher than that of the mountains on both sides of the basin, and the difference is significant. Difference is positively correlated with the intensity. When calculating the seismic intensity, it is necessary to consider the difference in the seismic geological background, but also to consider the complexity and homogeneity of the site conditions. If necessary, correct the calculated intensity. Finally, based on the attenuation relationship applied to the local area, a hypothetical earthquake is caused to cause loss of buildings, casualties, and direct economic losses. Finally, if the Hongdong earthquake in 1303 or the Linfen earthquake in 1695 is repeated, the anti-collapse capability of Linfen area will be comprehensively evaluated.
