This paper deeply studies the distribution,natures and cause of geofractures associated with the Heze Ms 7.0 and Ms 6(3)/(4) earthquakes in 1937,and their relation to the active faults near the epicentral area based on previous studies and field investigations. Then the fracture pattern 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 the Chengwu-Dongming buried fault which trends form NW to SE is mainly causative structure of the Ms 7.0 earthquake.
