| Abstract: | In this article, we have analysed the characteristics of small earthquake activity maps in the border area of Hei-Ji-Meng before all moderate-strong earthquakes occurred in Northeast China area since 1970. We have discovered that there is some significance of small earthquakes which may have impact to moderate-strong earthquakes on Nenjiang both side fracture. This result was preliminary analyzed combining with the geologic structure and some research achievements. |
