汶川8.0级地震后安徽省流体异常分布和地震活动特征

摘要

Based on the observed data of precursory underground fluid and those of macroscopic groundwater from macroscopic observation points in Anhui province, this paper analyzed the relationship between fluid anomaly distribution and fault structure, and studied on the possible influence of Wenehuan earthquake on Anhui province by teetonie characteristics. By using seismic data recorded by Anhui seismic network after the Wenehuan earthquake, this paper analyzed the relationship between seismic activity of main areas and fluid anomalies of concentration areas. Taking earthquake case as examples, this paper studied on the trend of seismic activity and area worthy of attention.%收集了汶川地震后安徽省前兆地下流体观测资料和各宏观观测点上报的宏观地下水变化资料.通过分析安徽省流体异常点的分布与断裂构造之间的关系,探讨汶川地震通过大地构造上的关联可能对安徽产生影响的敏感位置.还使用了汶川地震后安徽省地震台网记录的地震资料.分析了地震主体活动区域与流体异常集中区之间的关系,并结合震例,探讨了未来地震的活动趋势和值得关注区域.
