张北-尚义地震序列的空间分布、构造活动性初探

The preliminary study on epicenter distribution and tectonic activity of Zhangbei Shangyi earthquake sequence

利用张北－尚义地震极震区布设的微震仪所记录余震的精确定位结果，通过震中分布图，结合利用全球数字台网波形资料测定的震源参数结果，以及震区构造背景，对张北－尚义地震的发震构造及其构造活动性进行了初步探讨。

After Zhangbei Shangyi earthquake(1998,1,10),Beijing Telemetered Seismic Network(BTSN) arranged three microseismographs in the meizoseismal area during 10～20,Jan.,1998.Using the data obtained from field,we gave the accurate location of aftershocks.Through the epicenter distribution map、the seismic source parameters and the structural setting of earthquake area,the preliminary result of tectonic activity was given in this paper.
