On the base of comprehensive analysis of some new single-track seismic profiles and logging data, the neotectonic movement characteristics of the northern East China Sea Shelf Basin are researched. In the study area, there are intensive neotectonic movement. The main manifestations of the neotectonics include vertical movement, fracture activity and magma activity. The research indicate that the sedimentation centers shift from west to east since Miocene. NE-NNE-striking fault and EW-striking fault are the main active faults. The activity of these faults are gradually later from west to east. The magma activity are frequent and can be divided into three phases in the neotectonic period . They are mainly distribute along active faults. From west to east, the magma activity phases are gradually later. The intrusion gradually weaken and eruption gradually strengthen.
