历史地震核查中综合确定等烈度线方法
A method for comprehensively determining isoseismal lines of historical earthquakes:A case study of the 1624 Zhenjiang earthquake
摘要
Abstract
This paper proposes a method for comprehensively determining isoseismal lines during historical earthquake verification,and applies it to the 1624 Zhenjiang earthquake.Based on the collection and compilation of records concerning this earthquake from local chronicles,official documents,and literary works,the reliability of the data is evaluated by considering the time of compilation,the process of documentation,and the clarity of described locations.According to the current Chinese Seismic Intensity Scale,intensities at different locations were assessed.For areas lacking historical records,the acceleration distribution within the earthquake-affected area is determined by referencing the seismic intensity attenuation relationship for the region.This is combined with site amplification data derived from seismic safety evaluations that account for engineering geological conditions,and by analogy with the isoseismal distribution from the damage survey of the 1979 Liyang M 6.0 earthquake,to comprehensively assess and determine the location of the intensity-Ⅴ isoseismal line of the 1624 Zhenjiang earthquake.Together with the previously determined intensity-Ⅵ isoseismal line,the intensity contour map of the 1624 Zhenjiang earthquake is completed.关键词
