摘要
结合历史地震及1970年以来的中小地震空间分布,讨论了海东区域地震的活动特征,该区域中强以上地震主要分布在一些大断裂附近,而中小地震呈随机分布状态。自1995年7月22日永登5.8级地震以来,需要关注未来强震趋势。
According to the distribution of middle- small earthquakes since 1970,seismic characteristics in Haidong area are discussed. The results show that middle- strong earthquakes mainly occurred near huge faults,and middle- small earthquakes present a random distribution. The strong earthquakes should be paid more attention since Yongdeng M5. 8 earthquake on July 22,1995.
