【摘要】 利用云南中东部地区多年来有关的地震地质、地球物理、地壳形变等方面的研究成果,分析选定了15个与强震较为相关的特征标志,并通过图像识别方法最终筛选出12 个标志作为特征参数。通过综合图像识别在100个研究对象中得到了47个M≥6地震的潜在震源区,再在确定出的有可能发生及原已发生过6级地震的49个研究区中识别出27 个M≥7 地震的潜在震源区,给出了云南中东部地区中强震潜在震源区预测图。更多还原

【Abstract】 Based on the data of seismogeology,geophysics and crustal deformation in contral and eastern Yunnan province in recent years,the 15 characteristic parameters which are closely correlated to strong earthquakes are analysed and selected. Among the 15 parameters,12 are choosed by sieving method of pattern distinction as the final parameters. Using the means of synthetic pattern distinction, 47 potential seismic focus areas for M≥ 6 earthquake from 100 studying areas are determined. Then,27 potential seismic focus areas for M≥7 earthquake are obtained from 49 studying areas in which the M 6 earthquakes have occurred or will occure possibilly. On this foundation, a predictive map of potential seismic source areas for moderate-strong earthquake in Central and eastern Yunnan province is put forward.更多还原
