【摘要】 根据历史文献记载 ,我国历次正式出版的地震目录 ,皆将此次地震审定为M5 ,宏观震中为41 8°N ,1 2 3 4°E ,震中烈度为Ⅶ度。为进一步核实此次地震的参数 ,笔者查阅了已发表的有关资料 ,调阅了辽宁省档案馆 3 0卷历史档案 ,以确定文献中提供的破坏点的具体位置 ,统计了近、现代中强地震的烈度分布和人员伤亡情况 ,咨询了有关专家。经进一步研究认为 ,历次出版物对这次地震宏观震中位置和震中烈度的认定是合适的 ,但Ⅶ度区范围较笼统。我们依据历史地震烈度评定原则 ,确定了各破坏点的烈度 ,圈定了Ⅶ度区的范围 ,宏观震中在Ⅶ度区内 ,地震发生在当时的沈阳市区 ;根据极震区建筑物破坏程度和极震区长轴尺度、现代中强地震的震中烈度和人员伤亡情况 ,并考虑到确定历史地震的误差 ,震级取M5 较为合理。更多还原

【Abstract】 On the Basis of historic documents,magnitude of the Shenyang earthguake of March 15,1765 was examined to be M=51/2,its epicenter was 41.8°N,123.4°E,epicentral intensity wasⅦ in all previous publication of our country.In order to cheek its parameters of this event,the author consulted published historic data,and studied intensity distributions and casualtes of modern earthquakes. It is showed that firmly believed epicenter and its intensity in previous publication is suitable,but extent of its Ⅶ intensity should be reduced,and its major axis approximately is 9～10 km,on the basis of damaged level and extent of buildings in epicentral region,and of epicentral intensity and casualties of modern events,magnitude M51/4 of the earthquake is adopted to be appropriate.更多还原
