| 摘 要： | 由统计单元(29°~34.5°N,110~123°E)中强震活动性分析,可以看出安徽省中强震的发生呈现出300年大周期的特征,而安徽未来10年处于中强震的300年周期中的弱活动周期内。结合安徽省地震地质构造背景分析,认为安徽省未来中强震活动场所以32°N以南为主,并且重点应关注六安—霍山地区。其次,安徽西北阜阳一带新构造活动特征及历史地震活动特征显示该区存在构造地震空区,未来有发生中强震的地震地质背景。

| Abstract: | Anhui province is in moderate-strong earthquake area whose activity level is not high.The moderate-strong earthquake activity period is about 300 years through the analysis of earthquake activity characteristics in statistical unit,and Anhui province next 10 years is in the weak activity stage of 300 years period.The place around south latitude 32 line of Anhui province should be taken an attention based on the analysis of seismological structure background and moderate-strong earthquake activity of Anhui province,especially in the Luan and Huoshan area.Seismic gap is shown to exist in Fuyang and nearby area of Northwest in Anhui province which has the possibility of moderate-strong earthquake occurring by the study about neotectonic movement characteristics and historical earthquake activity behavior,and the area has the background of moderate-strong earthquake. |
