试论震情网络://c

本文在过去对震情窗口、震情地带作应用研究的基础上,根据一震有多窗、多带反应的观测事实,进一步提出并讨论了建立起结合窗、带而综合利用的震情网络的问题。为了方便,把它分成了一级和二级两个层次的网络,以便适用于长时间、大范围的大形势的趋势预报和短时间、小范围的短期预报。文中在简单讨论了震情网络的物理意义后认为,应用这种简便易行的办法来观察和提取大地震前面上的震兆信息,以便在时间和空间上为震情趋势的分析判断提供可靠的依据,无疑具有它一定的现实意义。 

ON THE SEISMIC SITUATION NETWORK METHOD

In this paper, based on the previous study of practical use of seimic situation windows and seismic situation belts, the problem of establishing a seismic situation network consisting of windows and belts is further posed and discussed according to the observed fact that many windows and belts make responses to one earthquake. For the convenience of usage, the seismic situation network is divided into two classes, the first class and the second one. The former can be used in tendency prediction for long-term seismic activity in a large area, the latter used in shortterm prediction in a small area. In this paper, after briefly discussing the physical significance of seismic situation network, it is pointed out that this simple and easily used method can be used to observe and extract seismic precurssory information from a large area before a great earthquake, thus it can provide a reliable basis for the analysis and judgement of seismic situation tendency in time and space. No doult, this method is of certain practical significance.
