【摘要】 根据泰安地区主要断层进行系统研究,并分析历史地震、1970年后有仪器记载以来地震与断裂活动的相关性。结果表明,该区域所处地块在地质结构改变,岩石破裂方面,存在一个固定趋势的影响,而这种影响也作用到了地震事件的分布。在今后相当长的一段时间内,泰安地区地震趋势没有明显转折,依旧维持目前的趋势。持续的小震活动,是本地区4级左右中强震延迟孕育的有力证明依据。更多还原

【Abstract】 In this paper,the relationship between fault activity and historical and modern earthquake since 1970 in the Tai’an area are studied.The results show that there is a fixed tendency of the geological structure change,rock failure,which inflent the earthquake distribution in the area.In the next quite long period of time,the earthquake activity will still maintain the current trend and will not change obviously.Continuous activity of small earthquake indicates that the risk of earthquake about ML4 in this region is not big.更多还原
