对华北东部地震危险性的估计

ESTIMATE ON EARTHQUAKE RISK IN THE EASTERN NORTH CHINA

用灰色系统理论、可公度性理论对东北≥7级深震作了估计。同时利用东北深震与华北东部浅震具有一定的相关性和深震活动超前浅震活动这一现象,估计了华北东部地震的危险性。

This paper estimated the deep seismicity with M≥ 7 in Northeast China using the grey system theory and commensurability theory. Simultaneously, disccussed the seismic risk in eastern North China using the correlativity between the deep seismicity in Northeast China and shallow seismicity in the eastern North China as well as the phenomenon that the deep seismicity is earlier than the shallow seismicity.
