基于潮汐因子的河北省形变台站映震效能评估

Evaluation of Reflecting Earthquake Ability of Deformation Stations in Hebei Province Based on Tidal Factors

定点台站观测资料作为中短期地震预报的基础性资料,其质量好坏及台站映震效能对地震形势分析研判有重要作用。鉴于此,对"十五"网络化改造后,2008年以来河北省形变台站的观测资料进行潮汐因子计算及映震统计,通过梳理分析、归纳总结得出质量较好的形变台站及测项,用于辅助河北省地震形势研判。

The quality of observation data recorded by fixed stations and the reflecting earthquake ability of stations have a significant influence in seismic situation analysis and medium-short term earthquake prediction.Considering this,based on the observation data recorded by the deformation stations of Hebei Province since 2008(after the network reconstruction of the tenth"Five Year Plan"),the tidal factors are calculated and the reflecting earthquake ability of the stations are analyzed in the study.Through the analysis and summary,deformation stations and observation items with good quality are obtained,which are highly useful in studying the earthquake situation in Hebei Province.
