| Abstract: | The seismogeological characteristics in the Xiuyan-Haicheng MS5.6 earthquake area are discussed in this paper.The seismogenic structure of this earthquake is defined by analyzing epicentre distribution, pattern of isoseismal line, relation of earthquakes and faults, etc. The result shows that the Ms5.6 earthquake is still a earghquake in the Haicheng seismic region, the seismogenic structureof the Xiuyan-haicheng earthquake is the NW Haichenghe fault. |
