摘　　要：统计了1900年以来全球约2 200次6.0级以上地震,将数据分为ABC 3类,并给出了大震轻灾类地震的定义。对大震轻灾类地震进行提取,结合全球地震带的分布情况,划分国际大震轻灾类地震分布区域,给出国际大震轻灾类地震分布图。该图将全球划分为7个大震轻灾区域,初步分析,这些区域主要位于欧亚地震带最西段、印尼苏门答腊及附近海域和印尼班达海附近,环太平洋地震带的西南段、北段和南美秘鲁智利一带。About 2 200 earthquakes with magnitude over 6.0 are collected in this article. The data are classified into three categories ABC, and the definition of a class earthquake characterized by large magnitude and with light disaster is given and extracted. Combined with the distribution of global seismic zone, the distribution area of the large earthquake with light disaster is given and mapped. The map is divided into seven area, mainly located in the most western part of the Eurasian seismic zone, and near Indonesia′s Sumatra and Indonesia, Banda Sea near the southwest section of the circum-Pacific seismic belt, the North segments and South America Peru and Chile area.
