地磁特征线法是70年代初提出的一种以磁报震方法。该方法不仅分析、使用简便,物理意义清楚,而且有定量的预报指标及国内大量的震例,并在我区地震监测预报的应用中已收到良好效果。本文初探了兰州台地磁特征线法的参数异常与地震三要素的经验关系及在地震短期预报中的效果,并对该方法预报地震的某些问题进行了初步论证。 Geomagnetism characteristic method is a kind of method of magnetic earthquake reporting in the early 1970s. The method not only has the advantages of simple analysis, easy to use and clear physical meaning, but also quantitative forecasting index and a large number of earthquakes in China. It has received good results in the application of earthquake monitoring and prediction in our district. This paper first explores the empirical relationship between the parameter anomaly of Lanzhou station’s geomagnetic characteristic method and the three elements of the earthquake and its effect in the short-term earthquake prediction, and preliminarily demonstrates some of the problems predicted by this method.
