鲁西地震活动趋势分析
|
摘要
鲁西地处华北地台中南部，聊考断裂带纵贯南北，自有历史记载以来，还未发生过７级以上大震，但中强地震发育，小震活动频繁，具有较明显的周期性和条带分布特征。作者试图分析鲁西历史及现代地震的时间序列和空间分布，以期对鲁西地震形势有一个总体认识，对未来地震活动做一大致估计。
Luxi area is located in the middle south of Huabei platform and Liaokao fault zone passes through it from south to north.Since the time that there had the historical records,there havn't occurred large earthquakes with M S≥7 0,but the moderate earthquakes are well developed,small earthquakes occur frequently and have evident periodicity and zonal distribution feature.By analysing the time and space distribution features of earthquakes occurred at Luxi area,the author attempts to obtain a overall knowledge of Luxi seismic situation and have a rough estimate for the future seismic activity.
