宁夏同心地震窗开窗指标与中强地震关系

The Relationship between the Index of Tongxin Seismic Window Opening and Medium-Strong Earthquakes in Ningxia

本文应用两种方法系统地研究了宁夏同心地震窗的开窗指标,以及地震窗异常与宁夏及邻区的中强以上地震关系。首先应用molchan检验方法得出同心窗的地震能量开窗指标;接着应用传统地震学图像方法给出同心窗时空强开窗指标。两种方法都能通过预报效能检验,表明同心地震窗是宁夏测震学异常中较好的预测指标之一。最后,作者建议日常会商跟踪该异常一般采用第二种方法,因为该方法比较简便、有效和更加直观。

In this paper,two methods are used to study the opening index of Tongxin seismic window in Ningxia,and the relationship between Tongxin seismic window anomaly and the above me-dium-strong earthquakes in Ningxia and adjacent areas.Firstly,the seismic energy index of Tongxin window is obtained by using molchan test method.Then,the window opening indexes of Tongxin window time,space and intensity are given by the traditional seismic image method.These two methods can pass the test of prediction performance,showing that Tongxin seismic window is a better prediction index in Ningxia seismography anomaly.Finally,the author suggests that the second method should is generally adopted in daily consultation to track the anomaly,because it is simple,effective and more intuitive.
