在分析1966年邢台7.2级地震的构造背景基础上划定邢台地震窗的范围并选取地震资料,分析和计算了地震窗地震活动高频次异常对华北地区6级以上地震的预测效能。结果表明邢台地震窗高频次异常具有较高预测信度。
Based on the analysis of tectonic background of Xingtai MS7.2 earthquake in 1966,the range of Xingtai shock window is determined and the data of earthquake are selected.The predicting value of seismic high frequency anomaly in this shock window for M≥6.0 earthquakes in north China are analyzed and calculated.It is found that the high frequency anomaly showed better assessment of prediction efficiency.
