摘要
2002年8月21日至10月20日,华北地区发生了一组显著地震活动。通过该组显著地震活动的时空分布特点,分析了华北地区这一轮地震应力场的"聚""散"过程,讨论了华北块体北缘地震带及与之紧邻的内蒙古西乌珠穆沁旗地震区未来的活动趋势,所得认识对今后该区的震情动态跟踪监视、趋势估计乃至地震短期预测判断具有一定的现实意义。
There were a group of marked seismicities in North China, from Aug. 21, to Oct., 20, 2002. The gathering and dispersing process of seismic stress field of this turn in North China is analyzed, through viewing the feature of space-time distribution of this group of marked seismicities. The result from this study has practical significance for dynamic monitoring continuously, trend estimating and judging of short-term earthquake prediction.
