| 摘 要： | １９９８年１月１０日河北张北－尚义发生了６．２级地震。这次地震前大华北区域显示出明显的地震活动性异常，中国地震局给出了成功的中期预报，但没有作出短临预报，本文根据震前后地震活动特征，从大区域内提取地震学指标异常信息并通过ＧＬ值空间扫描确定地震震源区，取得了较理想的效果。

| Abstract: | A Ms6.2 earthquake occurred in Zhangbei Shangyi area of Hebei province in Jan 1,1998.Some obvious seismicity anomalies appeared in North China region before the event.China seismological Bureau had given a successful medium term prediction for this quake,but no imminent prediction.In this paper,according to the characters of local seismicity before the event,we pick up some seismological anomalies through Gl spatial scanning,and the focal region is determined.The result is ideal. |
