会昌地震台地形变观测资料分析
|
摘要
通过全面系统的收集、整理与分析研究江西省会昌地震台近十年来地形变观测资料,运用Nakai拟合、潮汐变化分析、加卸载响应比3种前兆数据处理方法,对台站地形变资料进行处理,拟合分析,并与台站异常有效评价范围内的地震联系在一起,分析地震前兆异常与地震之间的关系,归纳总结异常特征,为能够快速准确地捕捉地震前兆异常信息提供参考。
Through the comprehensive collection,arrangement and analysis of topographic variation observation data in recent ten years of Huichang seismic station,Using three methods including Nakai fitting analysis,tidal change analysis and plus unloading response ratio analysis,on basis of deformation observation data,and linking with abnormal effective evaluation earthquakes,we analyze the relationship between deformation anomaly and earthquake in Huichang Seismic Station area. Finally,We summarized the anomaly characteristics,in order to be able to quickly and accurately capture the seismic precursor information reference.
