摘　　要：本文研究了东北深震区深震括动的时序特征,发现深源地震活动具有较清晰的平静—活动轮回,并且在深震活动之后,黑龙江省的浅源地震活动相对增强。根据历史地震活动特征与近期小震分布特点,作者给出了未来十年时间内,浅源中强震发生的二条危险区段。This paper studied the time sequence features of the deep-seated seismicity in Northeast China deep-seated earthquake region and shows clearer cycle with alternate quiet and active periods, i. e, after deep-seated earthquake activity the shallow seismicity is relatively strengthened. From the active characteristics of historical and recent earthquakes, authors proposed two risky time-intervals during which moderate-strong shallow earthquakes may occur in future ten years.
