华北某些地区地震活动特征的研究
|
摘要
以中国强地震目录资料(中国地震局监测预报司预报管理处编,1999)为基础,统计研究了1300～1988年华北地区6级以上地震发生后,10年内再次发生5级以上地震的优势空间范围。根据这一统计特征,印证性地分析了10余年来华北的晋、冀、内蒙古交界地区至包头一带5级以上地震空间活动特点。另外还研究了1981年以来晋、冀、内蒙古交界地区与晋、冀、鲁、豫交界地区5级以上地震,以及1998年至2001年11月晋、冀、内蒙古交界地区与唐山地区地震活动的呼应关系,并对其成因作了初步讨论。
On the basis of catalogic data of strong earthquakes in China, we statistically studied the preponderant spatial ranges of recurrent earthquakes with magnitude over 5 within ten years, after the occurrence of earthquakes with magnitude over 6 in North China during the period from 1300 to 1988. Based on the statistic ch aracteristics, the spatial activity features of earthquakes with magnitude over 5 in the zone of the border land of Shanxi, Hebei, Inner Mongolia regions to Bao tou were verily analyzed for the recent decade. In addition, we studied the echo ic relations of earthquakes with magnitude over 5 in the border of Shanxi, Hebei , Inner Mongolia regions and the border land of Shanxi, Hebei, Shandong, Henan r egions since 1981, as well as that of earthquake activities in the border land o f Shanxi, Hebei, Inner Mongolia regions and the Tangshan region during the perio d from 1998 to November 2001. The cause of formation was primarily discussed.
