摘要
本文对安徽及邻区地震序列和地震地质构造进行了分析研究。结果表明,安徽及邻区具有较明显的地震类型分区特征,地震序列以主余型为主,孤立型次之。考虑地震活动性与活动构造、震源机制解等因素,可以将安徽及邻区划分为15个具有不同特点的分区,为地震应急工作中震后早期趋势判定提供参考依据。
Study on the earthquake sequences showed that Anhui province and its sur- rounding areas had obvious sub-area characteristics of earthquake types. The major-after- shock earthquake type sequence is dominant, isolated types aresecondary. Considering the factors of regional seismicity, seismic geological structure background, focal mechanism and so on, Anhui could be divided into 15 sub-areas with different characteristics to pro- vide the basis for the fast determination of earthquake trend.
