摘　　要：通过遥感、余震分布、现场考察等各种手段证实瑞昌北部存在一组至少切穿上地壳的北北西向断裂——武山隐伏断裂,并认为九江-瑞昌地震是北东向瑞昌-武宁断裂与武山隐伏断裂共同作用的结果。更具体地说,主震由瑞昌-武宁断裂控制,余震受武山隐伏断裂控制。Through a variety of means, such as remote sensing, distribution of aftershock and field exploration, it is proved that in the north to Ruichang there is a group of NNW fault——Wushan buried fault which dissecting through the upper crust at least and then it is proposed that the Jiujiang-ruichang earthquake may result from the NE Ruichang-Wuning fault together with the Wushan buried fault, concretely,the mainshock is controled by the former and the aftershock by the later.
