基于新生代活动构造背景的地震重点危险区域综合研究——以安徽为例

Synthesize research on the emphases earthquake risk area based on the background of the Cenozoic activity structure——A case study of Anhui Province

基于地震的发生与断裂的活动性密切相关,为了科学合理并尽可能准确地判定未来地震重点危险区域,以安徽为例,利用由深浅部对比、宏微观构造解析所给出的新生代构造活动性最新研究成果,结合地震活动性资料研究结果,对一些重点部位的地震危险性进行了综合研究。结果表明,根据长时间尺度的地质构造最新研究揭示的活动性较强区域,与根据近代地震活动性资料研究反映的危险性较大区域,呈现较好的一致性特征,从而为未来地震重点危险区域的判定提供了新的较为可靠的依据和方法。

Based on the close relationship between earthquake occurrence and activity of rupture and for determining the earthquake risk area scientifically and reasonably, we have synthetically researched the earthquake risk of the emphases part in Anhui Province, using the last researching production for the Cenozoic structure by the contrast with deep and shallow, macroscopic and microcosmic construction resolution, taking into account with the research result of earthquake activity. The result shows the coherence characteristic between the activity area of geologic construct and the recently earthquake activity. It provides a new credible gist and method to determine the earthquake risk area in the future.
