摘　　要：本文在前人研究和野外调查工作的基础上，对１９３７年菏泽７．ｏ级和子级地震地裂缝的空间展布特征、性质、成因及其与震中区附近活动断裂的关系进行了深入研究，并以此为依据对两次地震的破裂方式及发震构造进行了讨论，认为菏泽地震的破裂方式为“双震型共扼破裂”，北西向成武—东明隐伏断裂可能为７．Ｏ级地震的主要发震构造。This paper deeply studies the distribution,natures and cause of geofractures associatedwith the Heze Ms earthquakes in 1937,and their relation to the active faultsnear the epicentral area based on previous studies and field investigations. Then the fracturepattern and the causative structures of the two earthquakes are discussed.It is considered thatthe fracture pattern of the Heze earthquake is conjugate fracture of double-shock type and theChengwu-Dongming buried fault which trends form NW to SE is mainlv causative structure ofthe Ms 7.0 earthquake.
