摘要
本文讨论了东北深、浅源地震在时间上、强度上的相关活动特点,认为东北地震是太平洋板块俯冲与亚欧板块挤压作用的结果。东北深震超前于浅源地震活动,可为浅源地震监测预报提供信息。
Based on origin time of earthquakes and their magnitudes, the features ofinterrelated activity between deep and shallow earthquakes in North-Eastern Chinaare discussed. The paper shows that the earthquakes in the region may be causedby the pressed action between the dowlagoing slab of the Pacific ocean and theEurasian plate. The activities of deep earthquakes in the region usually precedeshallow earthquakes. Therefore they may give some information to shallow ear-thquake prediction.
