摘要
本文使用1960—1987年的京、津、唐、张地区地震台网的观测资料,采用文献[2]所述的地震空间集中度的计算方法,对所有资料进行了3种不同方式的处理。结果表明地震空间集中度的大小随时间、空间的变化明显地反映了地震活动图象的变化,并在一定程度上反映了地震活动平静、密集的变化过程。
All the data observed at the seismic network in Beijing-Tianjin-Tangshan-Zhangjiakouregion in the period of 1960-1987 have been processed in this paper, with three differentmethods on the bases of the computation algorithm concerning the spatial concentration ofearthquakes described in literature [1] . The results show that the spatial concentration valueof earthquakes reflects the seismicity pattern changes with time and space, and the variationprocesses of seismic quiescence and activation to a certain extent.
