After an earthquake,the earthquake disaster rapid assessment team needs very detailed information,such as an intensity distribution map.If we can study several kinds of different intensity distribution evaluation models in support of the emergency database and compare the difference between disaster evaluation results from different models,the final result will have greater credibility.In this study,the research area of focus was Chongqing and its adjacent areas.The research analyzed 19 earthquakes since 1960,collected and digitized 19seismic intensity isoseismal maps,and acquired a total of 46 isoseismal data sets,including long axis,short axis,and total area,for a data total of 141.In accordance with the characteristics of historical isoseismals,the isoseismals were processed as ovals.In this study,the researcher looked at the epicenter distribution of earthquakes in Chongqing and the vicinity,the intensity data,and the distribution of seismic magnitude and intensity.Through regression analysis,an intensity distribution evaluation model was developed on the basis of the seismic intensity attenuation relationship,and the results from the model were compared with those from other models,which yielded a figure representing the comparison.The attenuation relationship of the earthquake in Chongqing and its adjacent area was compared with Suyun Wang,in China＇s eastern region;Jianqi Lu,in a moderate earthquake area,and Jiancheng Lei,in Sichuan Basin.To make the seismic intensity attenuation curve closer to the actual situation with respect to far-field and near-field intensity,additional measures were needed to improve the distribution of the data.Hence,the author developed intensity distribution evaluation models based on the length of the prolate axis and the minor axis,and area statistics.The author developed different fitting curves for(1)magnitude V long shaft fitting,(2)magnitude V short axial fitting,(3)magnitude VI long shaft fitting,and(4)magnitude VI short axial fitting.Comparisons were made with one magnitude degree above the intensity area,for the intensity I relationship,and for the length of shaft radius ratio.Last,the author used the examples to verify the above three kinds of models.The model based on the attenuation relationship and the model based on＂Wang Jinglai＂ give intensity in two mutually perpendicular directions with distance attenuation,and the model based on the area is the seismic intensity distribution on the surface.The former two models are one-dimensional,and the third is two-dimensional.If an earthquake of grade IV or V happened in Chongqing and its adjacent areas,the author calculated three kinds of intensity distribution evaluation models,getting long and short axis radii.The first two models＇calculation results were more closely matched and so are deemed the best by the author.Because the sample size is small,we will expand the research area in the next study to include a destructive earthquake region.Furthermore,we will include methods of data correction in the earthquake disaster loss assessment process in order to more closely approximate the true mean variance regression relationship.The shape of the intensity distribution curve was very significant for the earthquake disaster loss assessment.
